I have been experiencing this problem for years on the last few OS's (Leopard to Mavericks), different laptops and a couple of iMac's. Randomly, when I'm trying to copy files from one folder to another folder (either on the same drive or network drive) I get the dreaded "The operation can t be completed because the item X is in use". I have tried renaming files, rebooting before I begging the copy, turned ideating on and off, I've used "What's keeping me", but it still gives me that error about half of the time. This is a huge inconvenience and I would really like to know if there is a true solution. You would think Apple would have solved this by now. I'm beyond fed up! Does anyone out here know of a way to solve this problem? Thanks!
