Can't Delete Files From My Book Live Cause They're In Use

Hello!

Recently I’m unable to delete some files from my book network drive. That’s because a system message pops up saying that they can’t be deleted because they are in use.

It’s weird because it tells me that even when no application is running.

Tried to re-boot the drive, did not work.

I’m using OSX 10.8.2

What can I do? Can anyone help?

Thanks!

What type of files?

The application could be running on the background

Well,

Unfortunately, it does it with all sorts of files including empty folders (no hidden files in them).

I don’t really know what could cause this.

Thank you for your answer!
