Previously i had video file of 80gb, when i tried to move them all because of low space some files of 13gb wont move at all, when i try to move them the whole system goes down it becomes very very very slow one mouse click responds after 5 minutes.

that means i should not be able to copy all the files instead of only some files not being copied? however the tried removing read only property and tried copying again the same thing happens, it gets stuck nothing works
