I have a post download script that uses `crc32` for filenames. Since it's costly to run that while renaming files I was hoping FB would save that in xattr data alongside the metadata. Yet I don't see it in the .xattr directory:
net.filebot.filename
net.filebot.metadata
I don't see it store inside the file xattr either.

Is there a method I am missing?

I remember seeing a forum entry a few years back about crc32 and checking files over time but can't locate that now to reference.
Thank you.
