I have a few very large folders copied that have the exact same byte size as their originals, but different file counts (off by 1-10 items) than what they should have.

No errors were reported during the copying process. I'm guessing and hoping that these are merely some .DS_Store files that didn't copy over?

NOTE: These folders did require admin approval, which, to my knowledge proceeded without fail.

On small project folders using Git repos, a diff would not be difficult. Worst case scenario, I can download, install, and run a third party diff tool, but don't want to if I don't have to.

  1. Can anyone say to some degree of certainty that these nominal file count differences are just negligible hidden OS files?

  2. What are some common reasons these byte counts would be identical, but file counts be off? Is this an indexing issue?


I ran a third party diff tool (Kaleidoscope) which found no differences between the original folders and the destination folders. Still a mystery as to why the file counts would still be different.

  • Did you enable to view hidden files? tourkick.com/2012/mac-os-x-force-finder-to-show-hidden-files This may help you find hidden files. – netrox Apr 2 '13 at 23:23
  • Try an rsync -n which does not do anything to the target - and give us a link to Kaleidoscope so we can see what it does, – user151019 Apr 2 '13 at 23:26

    Also note .DS_Stores do take up space - one I looked at was 25k – user151019 Apr 2 '13 at 23:28
  • In order of their respective comments: 1. I always leave hidden files viewable. 2. www.kaleidoscopeapp.com 3. Thanks. I knew they take up disk space, but wasn't sure if/how the OS counted it in the folder info panels. – Old McStopher Apr 4 '13 at 3:35
