What is an _00_ file?

These segments contain metadata essential for video playback and are created by file splitting software to break large videos into smaller, manageable parts. When combined in the correct sequence, these segments reconstruct the original video file. The segment numbering system, starting with .00_, indicates the order of these segments within the larger file.

Check the Header: Open the file in a hex editor to inspect the first bytes:
