Quickly and easily find and compare file checksums (MD5, SHA-1, and more) with Marxio File Checksum Verifier

As technology progresses, it seems that we are continually downloading larger and larger files. The problem with download large files is that sometimes the file may get corrupt while downloading. Also, with the increase in file hosting websites, people are constantly uploading and mirroring popular files to download. The problem with downloading a file from an unofficial mirror is you don’t know if the file is the original (i.e it could have been tampered with before it was uploaded). To solve these two problems, file checksums are a popular way to test for file integrity, i.e. to make sure you downloaded the file properly or to make sure the file is in its original state.

How to use checksums is very easy. Just find out what the checksum (checksums can be of various types but MD5 and SHA-1 are the most popular ones) of the original file is (this information is usually available directly from the developer’s website or you can ask a reliable source) and compare it to the checksum you get from the file you downloaded. If the checksums match the file has been downloaded properly and/or the file has not been tampered with. The thing is, however, for some reason there is no reliable built in tool in Windows to find the checksums of files (none that I know of anyhow). So to help with the latter half of getting the checksum of the file you downloaded I am posting to tell you about an excellent free¬† tool by the name of Marxio File Checksum Verifier:

Marxio File Checksum Verifier (MFCV) is a simple and easy to use. What makes it so great and better than the competition? This…

  • It allows you to select which checksum type you want: MD4, MD5, SHA-1, SHA-256, SHA-384, SHA-512, RIPEMD-128, RIPEMD-160, HAVAL 256, TIGER 192, and CRC32;
  • You can drag + drop files (which you want to find the checksum of) onto MFCV program window or browse your computer for them;
  • You can enter a checksum value (which you attained from the developer’s website or a reliable source) to allow MFCV to automatically compare it with the checksum value MFCV finds;
  • MFCV allows you to copy to clipboard your results;
  • You can add an entry in your right click context menu for quick access to checksums;
  • MFCV is fast, standalone, and portable.

Check out how I used MFCV to determine, and compare, the MD5 checksum value of Paragon Partition Manager 9.5 Professional (a 119 MB file that was mirrored a thousand times over):

It took MFCV 4 seconds to find, compare, and return the results to me. Great program this is.

You can download Marxio File Checksum Verifier from the following link:

MFCV works on Windows Windows 2000/X/Vista/7

    I use HashTab which is a Windows shell extension or a Mac plug-in.

    In Windows it adds an extra tab option to the right-click Properties menu.

    HashtTab supports 15 different varieties of hash and does everything Marxio does (I think) but is not portable. Small bad news, I just visited their website and it’s no longer free for commercial use but is still is still free for personal use. You could probably find an older version on the net which is free for everyone.

    This is how you verify MD5 checksums on Windows
    The Easy Way (digestIT with GUI)

    digestIT is a graphical tool that should be easier to use for most Windows users.
    Download digestIT.
    Navigate in Windows Explorer to the directory where you saved/downloaded the OpenOffice.org archive.
    Right click the OpenOffice.org archive file in and select digestIT -> Verify MD5 Hash (or Calculate MD5 Hash).
    If you select “Verify MD5 Hash” then you will be able to copy and paste the MD5 from MD5Sum page (linked to on the latest download page). If the checksums match, you will see: “Digest matches. Verification succeeded.”
    If you select “Calculate MD5 Hash” then you will need to visually compare the calculated MD5 with the one listed on the MD5Sum page (linked to on the latest download page).

    Usually I only look for a checksum value with very big downloads which I have to burn on a cd. For example a new version of Ubuntu. You download the iso file. Then you must burn that file with a iso burner. And after that you can use that cd to install that new operating system. The size of such a download is about 690 MB. If the download is corrupt, you end up with a burned cd that won’t work and you can throw that cd away. On the download site of Ubuntu (and other Linux distributions) they usually mention the MD5 and other checksums.
    Until now I used Karen’s Hasher (for Win XP and for Vista) to check the MD5 checksum before burning the cd. Karen’s Hasher (also freeware!) is easy to use, but after reading this review, Marxio File Checksum Verifier seems to be still more userfriendly.
    Thanks for the review, Ashraf!

    @Janet Berg: No, no there is no need to check everything you download. In my opinion you should only check

    1) If the file your downloaded is really big and you think you did not properly download it. It is easy to check if your properly downloaded it or not by trying to run/install it and see if it works.

    or

    2) You download the file from an unofficial (meaning not from the developer – CNET is usually an official mirror) mirror.

    Yes if you download from the developer’s website you should be fine unless you fall under case number 1 I just mentioned.

    This is all something I never heard about before….Should we be checking this out before downloading anything? Goatd downloads? Cnet? Etc? Or is this only for very-unknown mirrors? Can I assume if you download from the developers site, you wouldn’t need to check?

    @Janet Berg: Many developers actually don’t provide it (even though they should). The ones that provide it will usually show it somewhere near the download link. Otherwise writing to the company is probably best.

    I got the MD5 checksum for Paragon Partition Manager 9.5 Pro from a reliable source and double checked it with mine =).

  7. Janet Berg

    Where on developers’ sites to look? Couldn’t find a checksum value, for example, for Paragon Partition Manager 9.5 Professional on the Paragon site….Does one have to write to the company?

    Hello Ashraf,
    Please allow me to post this question, which is not related to the current topic. But it is very important to me to get the answer.
    I have follow one of your advise and use the Truecrypt program to protect my data. Recently I ran into a situation that I cannot access one Excell file within the Truecrypt holder. I got an error “Excel cannot access ‘JBV VIP.2009.xls’. The document may be read-only or encrypted”
    I cannot copy it out of the Truecrypt holder either. Do you have any advise of how to resolve this? many thanks in advance for your help.
