[Windows] EasyFileViewer will open almost any file type or format

EasyFileViewerHave you ever come across a file that you simply cannot open on your computer? This can be a pretty frustrating experience. Maybe you once had a program that could open this file type, or maybe you received the file from someone else and you never had a program that could open it! Regardless of how you got the file, the fact remains that you can’t open it. You can search online to find out what program you need to open it, or you can use EasyFileViewer.


Main Functionality

EasyFileViewer is a program that you can use to open tons of different file types, extensions and formats. It can open tons of different word processing file extensions, tons of file formats and even zipped folders. In short, this program can help you get rid of countless programs on your computer that you needed to open up different file types.


  • Supports the following file extensions: PDF, DOC, DOCX, XLS, XLSX, RTF, HTM, HTML, XML, TXT, LOG, and more
  • Supports the following picture formats: TIFF, JPG, JPEG, GIF, PNG, TIF, BMP and others
  • Can extract the following extensions: ZIP, 7Z, GZ, RAR and more
  • Allows you to copy text to paste into other documents or emails when dealing with word processing files
  • Allows you to search a document for keywords
  • Allows you to zoom in/out or rotate images you are viewing
  • When extracting files, you can choose to extract just one or all of the files


  • The program does not list all the extensions/file types that it works on. It worked on all formats that I tried, but it would be nice to have a full list
  • Although it allows you to “open” just about any file type, you are very limited to what you can do with these files once opened
  • Editing most of the opened documents would still require you to download the required program (unless you copied and pasted the information into a file format that you can edit)
  • You need to provide your email address to activate the program for 1 year
  • Is unclear if the program is free for 1 year only or free forever


EasyFileViewer OptionsEasyFileViewer is a great program for what it is, and what it is, is a file “viewer”. Sure you can interact a bit with the files that you open, but you are very limited as to what you can do with them. I point this out to keep people from being under the impression that this program allows you to open and edit any file type you want.

The biggest problem I have with this program is that I have no idea what file extensions it works on. It worked for all of the ones I tried, but when looking at the site to find a list of extensions that it could open, I was given this: DF, DOC, DOCX, XLS, XLSX, RTF, HTM, HTML, XML, TXT, LOG and more. It is the “and more” that is not extremely helpful. That being said, this is still a pretty impressive list of file formats that it can work with, and that does not even include the zip files (ZIP, 7Z, GZ, RAR “and more”) and image files (TIFF, JPG, JPEG, GIF, PNG, TIF, BMP “and more”) it works with. Maybe dotTech members can help test this program with other file formats that I don’t have. Of course, since this program seems to work on more files than it doesn’t, it may be easier to list the file format’s it doesn’t work with. I have yet to come across a file it wouldn’t open, so I will be interested to see what the users here can come up with.

Now, once you open a file, you are able to interact with the file a little bit. For example, you can actually select and copy text from files. This is pretty impressive, as it allows you to copy text from a file that you used to not even be able to open. Although it won’t let you edit the text, you could always paste the copied text into a word processing program that you do have, and edit it there.

As for images, you have the ability to zoom in and out of, as well as rotate, the image. It works like a standard picture viewer, and you have no ability to edit the pictures at all. However, at least you can now open pictures that you may have been unable to open before.

I found it most helpful as an unzipper. It was able to successfully unzip the three file types I tried: RAR, ZIP and 7Z. That being said, the program also claims to work on GZ, which I was not able to test, but I assume it works just fine. When you go to unzip, you can choose to unzip one or all of the files in the archive.


Overall, I feel this is a pretty good file viewer. Although you are limited as to what you can do with the files you are viewing, I felt that it gave me enough freedom to justify a download. The biggest problem is that the developers did not list a full list of file extensions this program works with. Maybe they didn’t because it was simply too long. If that was the case, I would have just preferred a list of extensions it did not work with. Either way, this is a great program for people who have files on their computer they simply cannot open.

    @David Roper:
    I use Total UnInstall. Immediately after I install a program, I check it out by running it. If I don’t like it, I immediately use TUn to wipe it out. I have had great success with that tactic. I believe that TUn will handle an uninstall just fine at a much later time, but I really trust that it will do a great job without screwing up any other program or the registry if I do the uninstall right away. So, I won’t bother to let this marginally useful program sit on my computer for even a few days.

    I notice that the program authors have not bothered to show up here. Sad. Perhaps they have not yet seen this article. If and when they do, I hope they write something here to address the concerns we have expressed..

  • David Roper

    I agree with AFPhys in that the registration process was ridiculously difficult and as soon as the “Free” one year license is over, it had better be extended for free or it gets wiped. I don’t like their tactics. As the girl said “Ain’t nobody got time for this.”

  • AFPhys

    Hi All, @Justin: @Ashraf: @Harold:

    I am glad to see these comments today. I installed and uninstalled after seeing the preview, and didn’t even go so far as trying to “get a free 1-yr license”. I found out that I had to get a license when I tried to look at the two files: *jpg (success), *csv (surprisingly unsuccessful since that is a simple text file). With the preview garbage going on, and already a 50% failure rate, I immediately uninstalled and forgot to come back to DotTech to report though I intended to do so. I am glad that Harold did, and I thank him.

    One lesson I am taking away – when there is a registration surprisingly required for a program to be used, I get very testy about having it on my machine and I have to be a little patient. I hope that when that is required in the future, I notice it, and I hope DotTech flags that requirement in their reviews.

    For the creators of the program: This is the type of program I would only want around “just in case” I need it, and would normally try only as a last resort. Since that is the case, any type of expiration date associated with the program makes me MUCH less likely to get the program and keep it since it is likely I may not even use it before the license expires. Unless they respond to this note, I will not be installing it again.

  • Ashraf

    @Harold: @Justin: I, for one, and happy to see we were all able to put our heads together and figure out the solution. Thank you Justin, Harold, and everyone else!

    @David Roper: You are welcome!

  • David Roper

    Thanks Harold and Ashraf. I jumped out of the room too quickly. I’m getting this again.

  • @Harold: Great, I am glad we got it worked out for you. The phone number is misleading in the email and I should have covered that you don’t have to call them in my review, my apologies.

    Anyway, thanks for the information! It is great to see what files people are having or are not having success opening with this program.


  • Harold

    Thanks for the follow-up on this. I guess I didn’t scroll down far enough–I stopped when I saw them saying I had to phone.

    At the bottom of the page there was an activation code. Despite my extreme discomfort with a company that plays those kinds of games, I decided to complete installation of the software.

    The activation code worked and I have now tested the software. It does not let one view comma delineated (.csv) files, .wmv files, calendar (.ics) files, Microsoft Works database (.wdb) files, PowerPoint (.pptx and .pps) files, Open Document (.odb and .odt) files, or WordPerfect (.wpd) files, but it worked well on the other files I tried to view.

  • Ashraf

    @Tom: Thanks for the list.

    @Justin: I finally got their email, too. I can confirm this is exactly what is happening. You don’t have to call them. For some reason, they really want you to, though.

  • Ashraf

    @Justin: Thank you Justin. That should clear everything up.

  • Hi everyone,

    I just got done going over the email I received when I installed (took me a bit of time to find it LOL). Anyways, I see where Harold got confused now. In the email it does give you a BIG phone number that says call to activate your software. However, this is really just a stunt to get you to call and they will “help” activate it. You can do it yourself, as I did.

    Just under the phone number in the email is a heading that says “Get You Free Subscription License Key” with a link that says click here. This link will take you to another page. You will see the phone number again, ignore it, and scroll down a bit and you will see your free key that you can enter yourself (as I did)

    To enter the key, open up the program, click on the help menu, and click on About EasyFileViewer and enter the key that they gave you and enjoy your free year subscription.

    I should of been more clear about the email part. It was my mistake, but I am so used to actually reading the emails that I didn’t even mess around with the phone number and just went right to the page where it gave me my key.

    Hope this helps!

  • Ashraf

    @Harold: I see where it asks us to register with our email, but I am still waiting on their email to be sent to me so I cannot confirm or deny this behavior. However, I’m sure Justin would have notified us of this behavior. Something might of wrong had happened at your own.

    I’ll update when I learn more.

  • @Harold: Thanks for the info Harold, however I am a bit confused. I still have the program installed now and was not forced to do all of this. To activate the “year subscription” (which is free) I did have to provide a email address, but was never told to call a phone number. Had this happen to me I would of warned everyone to stay away, as I am against “shady” companies.

    As I can’t update articles after they have been posted, we will have to wait for Ashraf’s feedback.

  • Jim Carter

    @Harold: Thanks for the info!

  • David Roper

    As They say” I..am..outta..here”. What a pity. Ashraf, maybe you can chime in on this?

  • Harold

    Justin, you have let your readers down! You say nothing about the onerous activation plan for this “free” program. When I installed the program it turned out to be a “preview only”. To activate the program requires obtaining a one-year subscription by providing name and e-mail address. Although I was hesitant, because of the positive dottech review I finally decided to proceed. I expected to receive the activation number by e-mail, but to my surprise I received an e-mail that said, “activate your new software by calling (888) 312-9268”. The email also had a line that said, “EasyFileViewer: To get a license key for your software click here.” When I clicked on that link it took me to a web page that repeated the need to call their activation number. It elaborated on that instruction as follows:

    “To quickly activate your software, call us toll-free at the number above. Our technicians will securely connect to your PC and remotely activate your software for you. At your request, we will also diagnose your PC for other hard-to-identify problems.”

    In this day of security threats, why would anyone trust an unknown company enough to let them connect to their PC to activate software and “diagnose” problems? I find this totally unacceptable & will avoid this company like the plague!

    I am disappointed that your review failed to warn us of this inappropriate company behavior.

    I am with AFPhys on this. It is that Swiss Army Knife that it’s better to own than NOT to own. I only wish it was Portable so I could stash it away on my thumb drive and make my friend in Australia happy.

  • AFPhys

    I have run across a few formats over the years that I’ve been forced to open as text/hex only. I don’t recall right now what they were. I’m going to snatch this now to use the next time. It may be a long time before you get the feedback and assistance you want, though, since I’m not going on a specific quest to figure out what it won’t open, and you have covered all the most important already, Justin.
