Command-line tool for finding out who is locking a file
Handle should do the trick.
Ever wondered which program has a particular file or directory open? Now you can find out. Handle is a utility that displays information about open handles for any process in the system. You can use it to see the programs that have a file open, or to see the object types and names of all the handles of a program.

If you want to find what program has a handle on a certain file, run this from the directory that Handle.exe is extracted to. Unless you've added Handle.exe to the PATH environment variable. And the file path is C:\path\path\file.txt", run this:
handle "C:\path\path\file.txt"This will tell you what process(es) have the file (or folder) locked.
