I'm reposting this thread because I put it in the wrong area - sorry about that. Somebody posted this in the 10.8 long ago. I'm curious if people are having this error message when they are copying files around 10.10: "The operation cannot be completed because the item is in use" I get this when copying from my computer (iMac) to the Drobo - even when I've done a fresh reboot and there aren't any apps open. Is this a bug? Is there some way I can tell which app is using the file? I'm not sure what to do...the problem is quite severe for me and restarting or even logging out doesn't resolve it.
