Here's a manual way of doing it.
1. Start
2. Run
3. Type: command
4. To move into a directory type: cd c:\*** (The stars stand for your folder)
5. If you cannot access the folder because it has spaces for example Program
Files or Kazaa Lite folder you have to do the following. Instead of typing in the fullfolder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1
6. Once you’re in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
7. Now to delete the file type in Del***.bmp, txt, jpg, avi, etc...
