Video files have the potential to take up quite a bit of hard disk space and creating, editing, or downloading them can be an arduous and time-consuming task. All the more so if it’s original content. This makes it all the more painful if your videos end up accidentally deleted.

What is an AVI File

AVI is short for Audio Video Interleave and is one of the most popular video file types around. It was developed by Microsoft towards the tail-end of 1992 and is an offshoot of the RIFF (Resource Interchange File Format) format introduced the year before. AVI is often used to house high-quality multimedia content and generally features less compression than other popular video files extensions, like .mp4 or .mov.

This means that AVI files usually take up a lot of hard disk space. However, it remains one of the more heavily used video extensions in the world today. This is because it allows for the storage and playback of both video and audio, which is encoded through multiple different codecs.

How To Recover Deleted AVI Files

Due to their large size, AVI files are typically kept on a backup drive where they can be accessed whenever needed. But even if they’re not utilized often, these videos can still be subject to various data loss scenarios, including accidental deletion, formatting, storage media corruption, and more.

How to Repair Corrupted AVI Files That are Not Playing

Once you recover your AVI files, it’s not uncommon for some of them to be broken and unplayable. Fortunately, in a lot of cases, these videos can be repaired so they can be accessed once more.

Why an AVI File Could Be Corrupted

There are many reasons why an AVI file may become corrupted. The drive it’s stored on might end up with some bad sectors, a virus or malware may have gotten hold of it, or your computer could have incurred a power interruption while the video was being accessed. Whatever the reason, you can try repairing the AVI file by using the VLC app.

Repair AVI Files With VLC Media Player

VLC – short for VideoLAN Client – is one of the most popular video players around, thanks to its lightweight hardware requirements, loads of extra features, and its ability to play almost all kinds of audio and video file formats, usually without the need to download additional codecs. 

Plus, it’s completely free, which is always a great thing. But multimedia playback isn’t the only thing VLC is good for. It’s also a capable AVI repair tool, making the video files fit for watching once again. This feature usually comes into play whenever you try to open a corrupted/broken video file using the program. A pop-up will appear with the option to Build index then play

Select this option if you’d like VLC to attempt to fix corrupted AVI files, though it might take quite a while, depending on the size of the video. If you want to set up VLC to automatically repair corrupted/broken files whenever it accesses them, follow these steps:

  1. First, launch the VLC app and head to Tools > Preferences.VLC preferences.
  2. Next, head to the Input / Codecs section.
  3. Open the dropdown next to Damaged or incomplete AVI file and select Always fix.VLC fix a file.

Bear in mind that this process doesn’t make any changes to your actual AVI file. It only fixes the playback for that particular session in VLC. So if you try opening the same video with another playback program, it’ll likely still run into trouble.

How To Open AVI Files on Mac and Windows

Since the AVI video format was developed by Microsoft for playback on Windows devices, it’s not surprising that Mac’s default QuickTime multimedia player is incapable of viewing AVI files natively. 

Do yourself a favor and download the Mac version of VLC instead. It’s less hassle and is completely free of charge.

How To Open AVI Files on Mac.

Unlike Mac machines, Windows operating systems include a media player that can natively play AVI files. It’s their proprietary file extension, after all. You just need to double-click the file, and it should open up in the default Windows Media Player without issue. That being said, it’s still worth downloading and installing the VLC app, as it’s a superior media player overall.
