I dont know the exact name, but some programs totally lock the files, like Visual Studio shutil.copy('C:\\a\\test\\test.ncb','C:\\b\test.ncb') IOError: [Errno 13] Permission denied: 'C:\\a\\test\\test.ncb' As soon as I quit the application I can copy the file. (I am writing a backup software which saves the changed files every few minutes. If there was a slight possibility to copy a file which is written at the same moment and therefore not consistent this is still better than no backup) > > There shouldn't be anything preventing you from copying in-use files, or > even read-only files if that's what you meant: That's exactly my opinion! > > Although you can't move or delete an in-use file, AFAIK. this seems to be easier, you can use inuse.exe http://support.microsoft.com/kb/228930/en-us Daniel -- http://mail.python.org/mailman/listinfo/python-list
