.mov files recovery

I recovered some lost .mov files using disk drill. While recovering I saw that each .mov was in two parts-one with _filename.mov which is very small like 4 kb and the another one with filename.mov,which is almost the original size like 8 gb. While recovering the files disk drill shows both as recovered but I can't locate the _filename.mov file. Any suggestions as to what to do?

The underscore part is probably the resource fork of the file. The macOS Finder sees both parts together as one file. It’s kinda old school, and mostly deprecated.

For documents, the resource fork could contain some kinds of non-essential meta data.

4 kB is a default for the smallest file segment, so a 1 byte file would still occupy 4 kB of disk space.

macOS supports resource forks on Windows File Systems (FAT32 etc.) by creating a hidden file with the characters "._" added at the beginning of the file name, in the same directory as the data fork file.


Any suggestions as to what to do?

You can safely ignore that part, if the object is to rescue video data.
