I might be misunderstanding the problem, but... If Racket on Windows can't delete the directory because a file downstream of that directory is open, then Windows will not allow renaming the directory either. Is Racket opening some file in that directory and holding it open? Another possibility is that some other process has launched in that directory or is holding a file open in that directory. Process Explorer from Microsoft can be helpful in figuring out what process is holding open which files: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx David ____________________ Racket Users list: http://lists.racket-lang.org/users
