“On my recent trip to Scotland, I recorded many videos with my Canon digital camera. But when I tried to play them on my computer, none of them played; instead, they showed a .DAT extension, which was unknown to me.
So I reached out to a techie friend to help me understand and repair my videos. He explained what a .DAT file is, and how I can fix video files stored in .DAT file extension.”

You can lose videos captured on digital cameras and smartphones due to multiple factors. When a video appears saved in a .DAT extension, they are likely corrupted or were recorded improperly.
The .DAT file extension is an unprocessed format offered by many digital cameras. So when your video file is not completely processed it stores as a .DAT file. Because of any interruption in the recording process, if the file processing stops abruptly the video then gets stored in .DAT file extension and becomes unreadable by media players. This error can result from issues like power failure, SD card removal during filming, or camera malfunctions due to software or hardware issues, such as accidents.
Are There Any Reliable Ways to Fix Video File Stored in .DAT Extension?
If your corrupt video file was stored in the .DAT file format, there’s still hope. The methods provided below can definitely help you fix a video file stored in .DAT file extension.
Ways to Fix Video Files Stored in .DAT File Extension?
If you are here with the hope of fixing a video file in .DAT file extension, you won’t be disappointed. Hence, before you risk permanently losing irreplaceable footage of family trips, gatherings, or other life moments, there are a few things you must try.
Method 1: Reinsert the SD Card into Your Camera
One of the simplest ways to repair a corrupted .DAT file is to reinsert the SD card into your digital camera. Since this error occurs when you forcefully pull out your SD card, inserting it back properly may make sense. Some cameras also have an automatic feature that scans newly inserted memory cards for corrupted files and tries to fix them.
- Turn off your camera and reinsert the SD card in your camera.
- Now turn on your camera and wait to see if the .DAT file has been repaired.
This method can be effective if the corruption is minor and the camera’s internal repair mechanisms can address the issue. However, if the file is severely damaged, this approach may not be sufficient.
Method 2: Re-download the .DAT Files Again
Sometimes, video files can become corrupted during the transfer or download process due to connectivity or other issues. You can try fixing a .DAT video file by re-downloading or re-transferring it.
Re-downloading the file from the source will help you get its uncorrupted version.
Method 3: Use VLC Media Player’s AVI Repair Tool
We all know that VLC media player is the most popular and highly used free video player. But did you know that you can also use it to repair corrupted video files? Yes, while VLC is primarily designed for playing videos, there’s one feature in it that allows you to fix video files. But you can only use it for repairing .AVI files. So what about .DAT file or any other video file? In such a case, VLC will simply convert it into an AVI file and fix it.
Here’s how to use VLC’s AVI repair tool:
- First, create a duplicate file of your .DAT file.
- Open VLC and click on Open file. If the .DAT file does not appear in the list, drag and drop it into the window to open it.
- Now, from the menu bar, click the media to open the drop-down menu and click on Convert/Save.

- Then change the file extension from .DAT to .AVI.
- Now go to Tools and then click on Preferences.

- In the “Input / Codecs” section, find the “Repair AVI Files” option and select “Always fix.”

- Save the settings and try to open the .AVI file in VLC.
VLC’s AVI repair tool might be able to fix the video and audio data from the corrupted file. However, this is not a guaranteed solution. So if you are either unable to open your .DAT file in VLC or unable to play it with the steps provided above, don’t panic, because there are still other methods left to try.
