I was mistaken. The English curriculum really needs to be stepped up in this country.
Did you reinstall in a new partition, do an in-place install, or reformat the existing partition? If the latter, all your data is gone. If the first, it should still be accessible either on your original partition or through your original installation. If you did an in place installation to replace damaged system files, things should be accessible under the original username in the Documents and Settings folder.
You've used 20 of 60 GB?
Did you run the dir command for the folder in question, and it listed the files within it?
I'm afraid your prose leaves me too confused. Generally speaking, if you had simply asked, "How do I recover files in a bad windows installation?" I would tell you,
"Get an external hard drive to which you can back up your files, download and burn a knoppix CD. Boot from the CD into Knoppix, mount your Windows partition, and copy the files you wish to keep to the external hard drive. Then, reformat and reinstall Windows.
