I'm trying to free up space on C: drive, and I've done it everywhere other than C;|windows directory. There are a load of directories that are of the format $NTuninstallnnnnn$. What are they, and can I get rid of them?
Same with a directory called $hf_mig$ that has about 50 subdirectories of the format KBnnnnn
Can I delete them manually, or is there a general cleanup program I can run?
