What is a REC file?

A REC file contains video recorded by a Topfield PVR digital video recorder (DVR), a device used to record standard and high-definition television programming. It is saved in a proprietary compressed format you can view with a Topfield PVR device or with various third-party video players.

More Information

You will likely only encounter a REC file if you own a Topfield PVR digital video recorder and have recorded TV programming, such as a show or movie, then transferred it from the digital video recorder to a computer. However, you may also receive a REC video file via email, USB device, or cloud storage service from someone who owns a Topfield PVR digital video recorder.

NOTE: REC files are also known as Toppy files since Toppy is short for Topfield.

fsck Data Recovery File

A REC file may also be a data recovery file created by fsck, a utility used to check the integrity of a file system in Unix and Unix-like operating systems. It contains a log of "inconsistencies" in a filesystem that were detected during an fsck check that can be analyzed by users to investigate issues in a file system. REC files are similar to .chk files created by the "CHKDSK" system tool for Windows.

More Information

The fsck tool is typically used in Unix-like operating systems, such as Linux, macOS, Free BSD. The utility typically runs during the bootup of the operating system to check the consistency of the filesystem. If the utility finds any issues, it logs them in one or more REC files to be analyzed.

When fsck creates REC files it names them as FSCK####.REC with the #### ascending from 0000 for each data recovery file created. For example, the first REC file is FSCK0000.REC, the second is FSCK0001.REC, the third is FSCK0002.REC, and so on.

REC files store data in plain text and can be opened with a text editor, such as Apple TextEdit or gedit. The files can also be deleted without affecting the performance of the system but they may be regenerated during the operating system bootup process.

NOTE: fsck is short for File System Consistency Check.
