Hard drive Clearing

Ok, I took out the hard drive of my computer and moved it to a hard drive enclosure. Now, I just want to use the hard drive for storage of documents and media (music, videos, etc.) All the the files from the windows is on it and it takes up quite a bit of storage. I want to removed them but keep the media files. I put everyrthing I wanted to keep in a seperate folder. Just right-clicking and deleting won't work. How can I remove these unwanted files and programs? Thank you.
