How to get extensive filesystem information about a file?
I have a file that consistently causes errors in my backup utility (Unison). I'm trying to narrow down a bug and find out how it is different from other files. I copied that file and a copy backups fine so bug is not related to file contents. Then I renamed original to make sure a bug is not related to a filename.
So now I have 2 files with exact same contents, same xattrs (I checked) but one of them causes backup to fail. What else could be different between those files?
Also it is not a single case. I have many similar problem files all of which are created by the same program (DaVinci Resolve)
update: I found out that while files show the exact same size in
ls -l the problem file has larger size in Finder 'Get Info' dialog. So there is some king of metadata attached to that file. How to view it?
update2: I tried to use
ls -l@ as advised but didn't get an answer. It just shows that file sizes are different but didn't show why. Here is some additional info:

As you can see
src.mov has different size in
mdls while for
copy.mov they are the same.
