I used to have a Macbook, but after two years the hard drive crash, I now have a pro. After getting the files that I needed back I went into my external hard drive that my old macbook backed up onto and tried to delete all of the old back ups so I could make room for my new computer to use. After deleting it one file is left in my trash can. It is an old back up from August and the file name ends with .inProgress. I assume that i must have disconnected my computer or something while it was backing up, but now when i try to clear the trash it says "The operation cant be completed because the item AGQ0qILU99QsKv is in use." I have no idea what that item is, where it is because it doesnt show in the trash, or how to get rid of it. I have tried to secure empty trash and use a few terminal commands but nothing is working. Also it wont let me remove it from the trash. It just copies the file rather than moving it out. Does anyone know what I can do?
