Frequently asked questions

Why would a file not delete on Windows?
A program has the file open, permission denied, or the file is locked by a system process. Close the program and take ownership first.
How do I find what is using a file?
Resource Monitor (resmon) can show handles. Open resmon, CPU tab, Associated Handles, search for the filename. Or close likely programs and try again.
When should I use Safe Mode to delete?
When closing programs and taking ownership do not work. Safe Mode runs fewer processes, so the file may not be locked.
