What is a REC file?
A .REC file is a data file that contains recorded information. Because many different programs use the .REC extension, it can hold different types of data. Common uses include match replays from Rainbow Six Siege and automation macros from JitBit Macro Recorder or TinyTask.
It is also used as a Topfield PVR Recording file by Topfield devices, a Brazilian tax declaration receipt from the Receita Federal do Brasil, a camera configuration file for Nikon ViewNX-i, or an eJuice Me Up recipe. Finally, system utilities like `fsck` save recovered file fragments with the .REC extension.
How to open REC files?
To open a .REC file, you usually need the original software. For game replays, load them directly inside Rainbow Six Siege. For Topfield PVR Recording files, you can play them using media players like VLC media player. Recovered files from `fsck` often contain plain text or JPEG images, which you can inspect with a standard text editor or hex editor.
Because the exact format is often unknown, viewer.online/rec can analyze .REC files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and troubleshooting
Do not rename the extension and expect the file to work. If you find a .REC file in a `lost+found` folder, it is likely a recovered file fragment rather than a video.
Software and tools
If your .REC file is a Topfield PVR Recording or a tax receipt, you might want to convert it to a standard format. We recommend file conversion to sensible target formats like MP4 or PDF on convert.guru.
Summary
viewer.online/rec is useful for identifying, inspecting, and understanding .REC files without installing software or dealing with compatibility problems.
