Today I installed my new SSD, but of course I don't want EVERYTHING installed on my 120GB SSD. I went into the registry and changed my default program file locations to my D drive ( The Hard drive ), and transferred all my programs to the new drive, but now when I try to remove the old program file folders ( c:\program files / c:\program files (x86) ) it says the file is being used in a program. Why? I changed the location and transferred the files? How can I correct this and clean the folders off of my SSD.
