Hi there, I copied a folder that's 276 GB big and has 432 files in it from one external HDD to another one. It tooks about 2 hours to transfer. Now just to make sure I looked up the folder information (⌘+i) of both folders. Strange thing is, that the new folder is 7 GB and 4 files short! It didn't give me any errors while transferring and I don't have the time to manually compare every single file. Is there an application that compares 2 folders and tells me what files are missing/different?
