I would like to know who is locking a file (win32). I know about WhoLockMe, but I would like a command-line tool which does more or less the same thing.
I also looked at this question, but it seems only applicable for files opened remotely.
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.
