I transfer a folder (230GB) from my external hard drive(transcend) to my macbook to clean it up, than i transfer the folder back to the external hard drive and i want׳d to delete the folder from the mac.. after i deleted the folder from the mac and clean it up i found that is deleted but the free space in my commuter is +230GB and it should be less 230GB!! and i can't find this folder in my computer. if anyone know how to resolve this problem pleas let me know best regards..
You probably have Time Machine turned on and this is Time Machine's local snapshots causing this. When you have TM on and delete a file and empty the trash the file is not really deleted, but it moved to a hidden /.Mobilebackups folder. If you turn TM off then back on the hidden folder's contents will be erased. Code: sudo du -hs /.MobileBackups If you run this command in Terminal it will show how much space is being used by that hidden folder (before you turn TM off then back on of course).
