The causes sound serious, but it’s not necessarily the case. Most of the time, you can trace the root of the problem back to a damaged index.

Because AVI is a sub-format of the Resource Interchange File Format (RIFF), it breaks data down into two blocks. Typically, these two blocks are indexed by an optional third block; it supplies the location of the data to the program that’s reading the file. This third block is usually the problem area.

Simply put, if you can fix the index, you’ve probably fixed the AVI file.

Two Methods for Fixing Broken AVI Files

A Google search will reveal several apps that claim to fix AVI files. In many cases their claims are accurate, but they’ll try and charge you a hefty fee if you want to save the fixed file.

Often, you’ll find a workaround to avoid paying the full fee, but why not save yourself the hassle? There are only two programs you need: DivFix++ and/or VLC Media Player.

I’m going to show you how to use each of them to fix AVI files.

Download: DivFix++
Download: VLC Media Player

DivFix++

DivFix++ hasn’t been updated for a few years, but it remains the most-used app for fixing AVI files, and it still works perfectly.

This guide will cover the Windows version of the app, but it’s also available on macOS and Linux.

To begin, grab a copy of the app from the developer’s website. The app comes packaged in a ZIP file. When you unzip it, you can use the EXE file straight away. You do not need to install it on your machine.

Open the app for the first time, and you’ll see a blank screen with just a few options. Pay attention to the three checkboxes in the lower right-hand corner.

How to Repair Broken AVI Files That Won't Play divfix strip copy

If your AVI won’t open, it’s worth making sure Cut Out Bad Parts is ticked. It’ll strip out parts of the video that cannot be salvaged, but at least you’ll be able to play and watch the remainder. It’s also smart to keep a copy of the original file.

Using DivFix++ to fix AVI files is a two-part process. Firstly, you need to strip out the old index. Click Add Files and point the app at your broken file. You can also click Check Errors before you start, but it’s an unnecessary step. If your file isn’t working, you just want to fix it as quickly as possible.

When you’ve added the file, it’ll show up in the Source Files box. You can add multiple files to create a queue. Next, click Strip Index.

If the process was successful, you’ll see a confirmation in the Log Window.

Now you need to rebuild the index and fix any other corrupted parts of the video. At the top of the app’s window, click the folder icon and select a destination for the new file. Next, click on Fix to get the process up and running. Depending on the size of the file and length of the video, it could take several minutes.

When the file is ready, you’ll once again see a confirmation in the Log Window.

That’s it; the newly-created file should play perfectly.

VLC Media Player

If you don’t want to use a DivFix++, you can often get results by using VLC Media Player instead. Any self-respecting tech geek should have a copy on their system because it’s packed with features 6 Awesome VLC Features You May Not Know About 6 Awesome VLC Features You May Not Know About There's a reason VLC is called the Swiss Army Knife of media players. This article identifies six awesome VLC features and explains how to use them. Read More . Like DivFix++, the app is available on macOS and Linux, but I’m going to focus on the Windows version.

If you try and open a broken AVI file within VLC, you’ll see an on-screen error message:

How to Repair Broken AVI Files That Won't Play vlc avi file error

Click Build index then play and let VLC do its thing. As the message suggests, it could take a long time.

If you have lots of broken AVI files and don’t want to regularly deal with the on-screen message, you can make VLC automatically fix files when you open them.

Open the VLC app and navigate to Tools > Preferences.

How to Repair Broken AVI Files That Won't Play vlc tools

In the new window, click on the tab labeled Inputs/Codecs and scroll down the to the Files section. Within Files, locate Damaged or incomplete AVI file and select Always fix from the drop-down menu. Click Save when you’re ready.

Note: Using VLC to fix AVI files does not alter the actual file. It merely temporarily fixes it by saving a new index in the app’s memory while the file is in use. If you try to watch the file in another media player, you’ll still encounter a playback error.

Which Tools Do You Use to Fix AVI Files?

This article has shown you how to use DivFix++ and VLC Media Player to fix broken AVI files. Follow the steps closely, and that evening with Game of Thrones will be back on track in no time.

    I saved few files thanks to this program but couldn't save most of them. When i launch the Fix command it says it isn't not an Avi file... while obviously they are Avi file of ca. 600mb each. I need to mention that when i go in Properties then in Details all the fields are empty (no video length, no frame, no width, no height, no bit rate NOTHING... except that it's an avi file of 600mb. Do you think i can still save those files ? Many thanks in advance.

    This only works on Divx files that's it. Nothing can repair your AVI files, at least here. Either re download a different file to replace your bad one, or just buy whatever it is.

      Honestly said Sir, nothing will help people to restore their badly injured AVI files (e.g. downloaded as torrents) to an original state (i have tried every single application, even premium ones and nothing helped at all), so don't waste your time and nerves. Buy a new one, cheers.

    I even tried an older one, they don't work. Hell the new one isn't shit compared to the old ones, but they still don't work It doesn't repair anything, it doesn't do anything. Hell mine is just an index problem and still didn't work. The older one I used even has a Rebuild Index option, and it still didn't work. You need to make a video in case people do it wrong, if not then you should just work at McDonalds or something

      What if your file is really have 24 min? and there 1 hour is free/corrupted/deleted? At least you can see that 24 minute now.

      Judging program by trying on 1-2 file is something sick. People needed to learn respect. If you don't like, don't use it. This not require to call that program as a waste. Now, all positive feed-backing people are wrong but you?

        Something sick? Obviously you've never seen someone die before. It's only for Divx files boy. Stop defending something you didn't create. This application is free. Free things don't always work. Hopefully you've learned that over these five years.

    Nope. Stripped index and applied fix but the file I have won''t be fixed. I'll stick with my usual applet; Avi Fixed (although that program did not work with the problem AVI either)

      December 12, 2009 at 6:54 am

      It's perfectly normal. It's "strip" button, not the "fix" button.
      If you have problems with the program (might be it could failed to fix one file) than fill the bug report.
      Some of people said that (at top) "bullshit, useless"... etc. If a program is not working, there is no way to downloaded 600.000 times. Or cannot became #1 search result at google if you search by "avi fix". Those people don't fill the bug report also... I think there a problem on that users, not program itself.

      It's simply working. Might be your file is not avi, or your system has some problems...
      You can fill tracker report for your problems.
      sourceforge.net/tracker/?group_id=170344&atid=853920
      Also you can send your "not working" avi file too for inspection. If program really doesn't work, than It will fixed. :)

    i tried 2 fix two seperate broken files, and they now play but look like crap and are still unwatchable. Does this mean the original file is broken, or it just didn't download correctly? The site i downloaded these movies from had 100's of good feedback from others so i'm going to delete the originals and try again.

      This means your AVI file broken or has unsupported codec. DivFix++ currently supports MPEG4 ASP and AVC streams plus VPx ans Sorenson codecs. I offer you FREE support for your 2 broken files if you upload them to internet and fill support request from
