[Review] File Defender 1.1

{rw_text}Giveaway of the day for February 17, 2009 is:

File Defender 1.1

Version Reviewed:


Software description as per GOTD:

File Defender is powerful and easy-to-use software that comprehensively protects all of your important files. The software creates encrypted executables, thus removing the need for the software to decrypt files on other computers.

Since the software is based on a very strong encryption algorithm, it is impossible to gain access to protected files without a password. It has a built-in key generator that creates absolutely unique combinations. File Defender is simple to use due to its seamless and user-friendly interface.

————————-{/rw_text} –>


  • Nice clean and easy to use interface.
  • Creates self executable/standalone encrypted files.
  • Encrypted files re-encrypt themselves after use.
  • You get to chose if you want to save/delete executables or original files.
  • Drag + Drop.
  • Can encrypt multiple files at once.
  • You can password protect File Defender.
  • Uses XTEA encryption – light on resources for slower/older computers.

{/rw_good} –>


  • Not Open Source.
  • Uses XTEA encryption – not the most secure out there.
  • When encrypting, passwords you enter are not hidden by default.
  • The original source file is not deleted by default.
  • You can’t add a ‘protected’ suffix.
  • When extracting file contents, the passwords you enter are not hidden by default.
  • You can’t extract file contents via standalone encrypted files.
  • Standalone encrypted EXE adds on ~650 KB to the file size.
  • The “Comment” box is placed very out of the way.
  • If you hit “X” on the window where you enter password the password for encrypting, the file will start encrypting.
  • You can’t chose where to place file once you encrypt it.
  • You can’t chose where to place file once you extract contents of encrypted file.
  • No context menu entry.
  • Self extractor doesn’t work well with videos (Vista only?)
  • If you try to extract more then one file at once, and the passwords are different of the files, you will get an error.

{/rw_bad} –>

{for=”Features as Described” value=”9″}Most everything works.
{for=”Ease of Use” value=”10″}Really can’t get any easier.
{for=”Usefulness” value=”10″}Come on admit it – there is always something you would like to send to someone that you don’t want someone else to see.

Registration and installation of this program went fine. This program does not officially support Vista but it works mostly so I assume it supports Vista. The only problem I ran into was that went trying to run a video from the standalone encrypted file – that would not work. This may be a Vista only thing it may not be someone please double check for me.

File Defender is an encryption software that uses XTEA 128-bit encryption. This is pretty unique seeing as most encryption software nowadays use Blowfish or AES. XTEA has its advantages in that it is ‘small’ algorithm wise and therefore will not be as computer resource intensive; thus it will run easier on older computers then some other encryption methods. However, the drawback to XTEA is that it is not he most secure. According to wikipedia, someone was able to break “26 out of 64 rounds” using a “key-related differential attack” back in 2004. In plain English, it is not as hack proof as, say, AES.

Update: I would like to remind people that AES is not 100% hacker proof either (nothing is), but  it is one of the strongest encryption standards out there.

The strength of File Defender is that it creates standalone encrypted files. What this means is that you do not need File Defender to decrypt and use the files that are encrypted. You can encrypt a file and send it to anyone. All they have to do is double click on the file, type in the password and the file will run. After they close the file, the file will be re-encrypted by itself.

The biggest weakness of File Defender would be the combination of the XTEA encryption method and the fact that it is not open source. When it comes to encryption and encryption software, open source is essential. Not only does it give the user peace of mind that the author has not malicious code involved in the encrypted software, but also (in a counter intuatitve way) it helps improve the security of the software.

That all being said, lets see File Defender before I say more about it. When you run the program, you will always be prompted with a little window asking you what mode you want to be in:


“Protect file” mode is the mode where you get to encrypt files. “Extract data from protected file” is the mode where you get to decrypt files. Both modes work in a similar manner user interface and how the programs work; they differ slightly in settings and such. This is “Protect file” mode:


Before I go into how it works, and how it works is pretty simple so there won’t be much going into, first what you want to do is make sure the settings are changed a little bit. You see there are two major security risks, in my opinion, with two settings that are on by default:

  • By default, when you are entering your password to encrypt files, the program does not hide your password with astricks. This is very bad in my opinion. So, before you do anything, go to View -> Settings and check “Hide protection passwords”.
  • By default the program is set so that when you encrypt a file, the original file is left in its place unencrypted and a standalone encrypted file for it is created. For example, you encrypt readme.txt which is located in your downloads folder. After you are done encrypting you will have readme.exe (which is the encrypted standalone)  in your downloads folder and you will still have readme.txt in your downloads folder. I personally think this is a security risk because one may forget to delete the original readme.txt therefore other people may access it. So, to avoid this, click on the “Settings” button. This will bring up the following window:


From this window, uncheck “Save original file”. Now, going back to the above example of readme.txt, when you encrypt readme.txt, you will only have readme.exe and not readme.txt. You can always come back and change these settings if you please.

Now that we have dealt with the house keeping, this program is pretty simple to use. Just add your files and hit “Protect”. You can add files either by clicking on the “Add File” button or you can drag + drop files into the main program window. Once you hit “Protect”, you will be prompted for your password. Type it in and hit “Continue”. The file will be encrypted and placed in the same location as the original file – you don’t get to chose where to place the file which in my opinion is a con. One thing to note is that at the window where you are typing in your password, if you hit “X” the file will start encrypting. Even if you have no password entered. This is really odd not in the fact that hitting “X” starts encrypting when it should close the window, but it also encrypts the file with no password! Another con.

So after you have encrypted a file, you can do whatever you want with it. You can send it to friends, keep it on your computer, whatever. Whenever someone double clicks on the file, they will be able to run the file – all they have to do is enter the password:


Notice that is says “No comments”. At this point you must be thinking “I never say a place to enter comments”. Well that is 100% true because the place to enter comments is hidden – you have to go to Settings -> SFX-Module tab and there you will find the comments box.

Anyway, back on topic, after the file is run and the user has closed it, the file will again be re-encrypted automatically. Pretty nice feature. However, there are two problems here:

  • For some reason, this program is unable to play video files that are encrypted. This may be only a Vista thing, it may not be – someone double check please. I get this error when trying to play an encrypted video file:


This error may occur with other types of files, I don’t know I obviously have no tested all types of files. However, out of the ones I have tested, images, text files and video files, this error only occured with video files – the other two opened perfectly.

  • There is no way to extract the contents of a standalone encrypted file unless you have File Defender. This, in my opinion, is a big con because if the strength of this program is that you can create standalone encrypted files that you can send to other people, they should be able to extract the contents of the files instead of having to type in the password and run/explore/use the contents of the encrypted file that way.

Besides just running the standalone encrypted file, if you want to extract the contents of the encrypted file, you can do that via File Defender. Remeber the “Extract data from protected file” mode from earlier? Ya it is its turn now. Run File Defender and chose that mode. You will see this:


Strikenly similar to the other mode don’t you think? =P. As with the other mode, you need to go in and change the password settings because by default the program does not hide the password you will have to enter when extracting the contents of an encrypted file. Again you can do this via View -> Settings.

Also similar to the other mode, when you decrypt a file and extract its contents, the original encrypted file is still there along with the extracted contents. Now this is not a security risk as was the other one, but it is annoying…to me anyway. If this is also annoying to you, you can turn it off from Settings again.

So similar to “Protect file” mode, you add your encrypted files here, and hit “Extract”. You can add the encrypted files via the “Add File” button or you can drag + drop. You will be prompted your password when extracting the contents of the file. However, the whole click-X-encrypt-file problem does not occur here for obvious reasons. When the file is done extracting the contents of it will be placed in the same location as the encrypted file. Again you can’t control where to put them.

One thing to note with the extracting is that if you can extract the contents of more then one encrypted file at once but if you do try to extract more then one encrypted file at once make sure that all the files share the same password. Otherwise you will run into an error after the first file or so. The error will just be that the file with the different password won’t extract and you will have to redo the process.

Besides all the above, just two more things I would like to point out:

  • You can password protect File Defender to prevent unauthorized access to it. You can do this via View -> Settings:


  • You don’t have to reload the program every time you want to switch the mode from protect to extract or vice versa. You can switch the modes by going to File -> Set Mode:


Lastly, before I move on I would like to point out that each encrypted file gains ~650KB in file size once encrypted. Apparently the EXE File Defender creates to protect/encrypt files is 650KB in size. Nothing too big but it is worth noting.

And that is the whole program basically. Overall, I like this program. Even thought does not officially support Vista and even though it has its fair share of problems, I give this a thumbs up. However, a thumbs up does not mean the program is error free. As you can see from my above writings, the program has problems. But, in my opinion, these are the biggest problems the developer needs to address:

  • The open source problem. Obviously this problem will be outstanding and will not be solved as long as this is a commercial product. However, maybe the developer can meet users midway by offering a freeware version of this program with the option to upgrade to a paid version with more features + guarantee that File Defender has absolute no Internet access.
  • Vista and Windows 7 support.
  • The developer needs to add the ability to extract files directly from the standalone encrypted files.
  • The developer should think about switched to a more secure encryption algorithm such as AES.
  • Add Windows context menu entries (right clicking on a file seeing “Encrypt with File Defender” there).


Windows XP Native File Encryption | Folder Encryption | Windows XP Native Decryption

For security purposes, this tool is only to be used for files that will be kept locally (i.e. on your computer). It may or may not (depending on the circumstances) keep a file encrypted if you send it (like via E-mail) to a different computer. Also note, if you copy or move a file to a computer or volume that does not use the NTFS file system, the file will be decrypted.

You can encrypt files only on volumes that are formatted with the NTFS file system. To encrypt a file:

  1. Click Start, point to All Programs, point to Accessories, and then click Windows Explorer.
  2. Locate the file that you want, right-click the file, and then click Properties.
  3. On the General tab, click Advanced.
  4. Under Compress or Encrypt attributes, select the Encrypt contents to secure data check box, and then click OK.
  5. Click OK. If the file is located in an unencrypted folder, you receive an Encryption Warning dialog box. Use one of the following steps:
  • If you want to encrypt only the file, click Encrypt the file only, and then click OK.
  • If you want to encrypt the file and the folder in which it is located, click Encrypt the file and the parent folder, and then click OK.

The EFS feature is not included in Microsoft Windows XP Home Edition.

Windows Vista Native Encryption/Decryption (If you have Vista Business, Enterprise, or Ultimate)

For security purposes, this tool is only to be used for files that will be kept locally (i.e. on your computer). It may or may not (depending on the circumstances) keep a file encrypted if you send it (like via E-mail) to a different computer. Also note, if you copy or move a file to a computer or volume that does not use the NTFS file system, the file will be decrypted.

To Encrypt a file or folder

  1. Right-click the folder or file you want to encrypt, and then click Properties.
  2. Click the General tab, and then click Advanced.
  3. Select the Encrypt contents to secure data check box, and then click OK.

To Decrypt a file or folder

  1. Right-click the folder or file you want to encrypt, and then click Properties.
  2. Click the General tab, and then click Advanced.
  3. Select the Encrypt contents to secure data check box, and then click OK.

Note: The first time you encrypt a folder or file, you should back up your encryption certificate. If your certificate and key are lost or damaged and you do not have a backup, you won’t be able to use the files that you have encrypted.


Protect your sensitive data with this free open-source disk encryption software.

Main Features (right off their website):

-TrueCrypt Developer


In other words: This program kicks ***. Get it, use it, love it. Click here to read CNET Reviews on TrueCrypt.

***Note: TrueCrypt has a huge learning curve, so it is recommended to read up on TrueCrypt here. To read up on how to use TrueCrypt visit the Beginner’s Guide. You can also view this video which shows you how to use TrueCrypt (thx Chris).


While the main purpose of this program is to replace programs like winRAR and Winzip, there is the ability to create .7z archived files that can be encrypted with AES 256.


TrueCrypt has an extremely big learning curve, but once you get to learn it, it is an amazing software. AxCrypt, on the other hand, is very simple to use and with AxCrypt you can encrypt or decrypt files very easily. The features are like Magical File Encrypt, with a few extras, like the ability to use a key file.

AxCrypt uses AES 128-bit encryption. For quick encryption, after you install AxCrypt, right click on the file you want to encrypt -> AxCrypt -> Encrypt. To decrypt, right click an encrypted file -> AxCrypt -> Encrypt.

The only one feature I question about AxCrypt is the ability to save passphrases (you have to opt in – I do not recommend it). Some inexperienced users might save their passphrase thinking it is secure, but they forget that if they save the passphrase anyone that comes to the computer and decrypt their files – with a saved passphrase you will not be prompted for a password! The passphrase is supposed to reset on boot though.

Overall, AxCrypt is a very hand open source program to encrypt single files on the go.

Update: AxCrypt also has the ability to create standalone encrypted files.

Kruptos 2

All the programs mentioned above, bar AxCrypt, are not ‘true alternatives’ to File Defender in the sense that they don’t offer an alternative to File Defender’s selling point – standalone encrypted files. Kruptos 2, however, does provide a user with the ability to create standalone encrypted files that will re-encrypt themselves. While Kruptos 2 is not open source either, it is freeware. It also uses AES 256 which is a much stronger algorithm then XTEA. Kruptos 2 also has the ability to ‘encrypt’ file names so it would be harder for people to find if you are trying to hide something. In general, I found Kruptos 2 to be superior to File Defender in every way. The only problem with Kruptos 2 is that it is not officially Vista supported (neither is File Defender by the way) – the developer even says on this website “please note Kruptos 2 is not VISTA compatible”. However, Kruptos 2 generally does work fine on Vista. The only problem I run into is when trying to run the contents of the standalone encrypted file – that never works properly. Everything else, encryption, decryption, etc. works fine. I am not sure if this problem is Vista specific or not.

{/rw_freea} –>

{rw_verdict2}I give File Defender a thumbs up. Yes it is not open source and yes it is not the most secure program, but it is simple, easy to use, and can come in handy for the home user who just needs basic encryption. As I said the strength of File Defender is the ability to create standalone encrypted files. There is no doubt that TrueCrypt is the king of encryption. For heavy, 100% safe, and high-stakes encryption needs, definitely go with TrueCrypt. However, File Defender is a different class of encryption software. The type that creates standalone encrypted files. In that sense, the only competition to File Defender is Kruptos 2. And in between these programs, I would find that Kruptos 2 is superior in every sense; however Kruptos 2 has those few issues that I mentioned above. As I said those issues may just be Vista related, so my suggestion for today is to check out Kruptos 2 first and see if you face the same issues. If you don’t go with Kruptos 2. If you do face the same issue, I say download File Defender and see which program you like better and keep that one.

Update: Apparently AxCrypt also has the ability to create standalone encrypted files. Thanks to redmaledeer for informing me…I never knew of that before today. A quick test of AxCrypt’s standalone encrypted file creation reveals it is superior to File Defender and Kruptos 2 in the sense that everything works perfectly and AxCrypt is open source; therefore my suggestion is get AxCrypt.

    I made an EXE for someone and named it dsfjksd.exeC,and gave intructions on deleting the C, and they couldn’t.
    Then I remembered .ZIP.

  • redmaledeer,

    I checked it out after you mentioned it and yes AxCrypt can create standalones.

    As for your idea or renaming the file, I was thinking the same thing. However, I have not tested it. In theory, if you did successfully rename the file (the only way I can think of via an FTP client – there are probably more ways), yes I think it may work. But that is a bit of a pain in my opinion. It is eventually up to the end user to weigh the pros and cons and decide what program they want to use – I can only tell you if a program is worth looking at or not.

  • redmaledeer

    Well, I right-clicked on a file, then clicked on AxCrypt in the resulting menu, and then on “Encrypt copy to .EXE”. I fed it a password and it duly made a .exe file. I double-clicked on that .exe file and gave it the password again, and apparently got the unencrypted file back.

    I also consider such a “standalone” property to be very useful.

    Incidentally, in regard to sending .exe files as attachments, and the possibility that these might be rejected as possible malware: Before sending, couldn’t one simply rename the file as .exefoo (or some such).

  • Does AxCrypt really have the ability to create standalone encrypted files? I never knew that.

  • redmaledeer

    Ashraf: “However, File Defender is a different class of encryption software. The type that creates standalone encrypted files. In that sense, the only competition to File Defender is Kruptos 2.”

    Perhaps I misunderstand the meaning of “standalone encrypted files,” but doesn’t AxCrypt make them too?

    Thanks for such a useful and informative Review and Response. I will file it for future reference.

  • Giovanni,

    You never cease to amaze me with your software list.

    deVault looks pretty nice. I am going to check it out. If it lives up to what it seems like, I am going to make a dedicated post on it.

    As a side note, can you please contact me? I want to talk to you about something. I would send you an email but I am not sure the email you used for your comment is your real email.

  • Giovanni

    Hi Ashraf,
    despite its current law user rating (39% THUMBS UP for this SW is sinply ludicrous…), I found this application pretty easy to use and quite complete (the ability to encrypt multiple files at once is not bad at all).

    Of course the biggest CON of this GAOTD is that it’s not OPEN SOURCE, so it’s not the most secure option available on the “market” as you rightly said in your review.

    OTHER GOOD FREEWARE ALTERNATIVES you may add on your review may be the following (all these programs are VISTA compatible and can be found on CNET or SOFTPEDIA websites…so don’t worry, you can try all of them as long as you have time to do so, of course…):

    – DPCRYPT 1.05

    – File Crypt 1.0.2

    – CryptoSidekick Personal (2048-bit RSA keys, 256-bit strong AES symmetric encryption)

    – iSafeguard Freeware 6.2 (secures your files and e-mails with strong encryption and digital signature)

    – ZNsoft Crypto 2.5

    -Flash Securer 1.1


    A program which allows you to secure the sensitive data you carry on your USB FLASH DRIVE: since the data is encrypted, your sensitive data won’t get into someone else’s hands even if the FLASH DRIVE is stolen or lost.

    – MyWinLocker 3


    A cool, light, and easy to use encryption tool with slick interface to encrypt or decrypt files with advanced encryption technologies (AES multiple file encryption, secure disk, password assistant manager, desktop search security etc….) which are accessible through a (VISTA) sidebar gadget or just by right-clicking on a specific file or folder.

    – Advanced File Security Basic 3.1.4

    A good encryption application to protect any type of data against unauthorized access using the world-wide standardized, fast and very safe encryption algorithm – AES. Usable with all kind of storage types such as Hard-Drives, CD/DVD, USB Sticks.

    – MEO File Encryption Software 1.10


    An excellent encryption application to encrypt or decrypt files of any type, including Microsoft Word, Excel and PDF documents as well as email, so as to protect your sensitive data against un-authorized viewers by utilizing the latest data encryption technologies



    What happens if your kids turn off your firewall then leave you unprotected whilst your computer is left online? Your files and data stored in your HD would be accessible to hackers or any other unauthorised users.

    To avoid this, this TOOL turns a section of your DRIVE into a protected and encrypted area, creating two Data Safes with 1 GB capacity each on your PC, Laptop, USB-Sticks, CDs, DVDs and so on, that is only accessible if you know the password required to access the encrypted DRIVE. In this way you can be sure that no one can get access on your personal data (photos, documents, music,video etc…) in case you forget your laptop somewhere or it’s stolen by thieves…LOL!!

    This program uses the Advanced Encryption Algorithm AES with 256 Bits helping you create HIGHLY SECURE PASSWORDS which you even don’t need to remember since you can use a USB-Stick for a key or a sequence of pictures with Steganos PicPass.

    – CryptDisk.4h


    An encryption utility based on a VIRTUAL DISK created by the program itself within a file: everything you write to the created virtual disk will be encrypted transparently and then decryption is automatic as CryptDisk.4h automatically decrypts the data before it is loaded, but when data is written back to the hard disk it is automatically re-encrypted using two of the most proven encryption algorithms: AES-256 and Twofish-256. Very easy to use as multiple drives can be easily managed from a simple list menu, not to mention that after mounting a drive files can be dropped in and removed using Windows Explorer or just the drag and drop function.

    – TRax File Guard 0.1b

    Finally if you need a small and handy application for creating unbreakable passwords in a few clicks, using 4 hash algorithms, “Aconiac Password Generator” is definetely one of the best solutions for this, as the password generator is very easy to install using very few resources indeed with the additional option to integrate in the user’s system a simple tool that can be opened when needed.


    Another application to create numeric, alphabetic, alphanumeric or even special character passwords with variable length is also Tukanas Password Generator 1:


    Waiting for your feedback.


  • Are we talking about a whole CD or DVD? You would need to compact the contents of the CD/DVD into one file then encrypt it with this program. However, I suggest TrueCrypt for CD/DVD.

  • internetexplorer

    Quick question–can this be used to encrypt files to be stored on CD or DVD (data and/or video), so they can’t be viewed without the password? Oops, 2nd question–is any free alternative better at protecting CD/DVD?
