I have a ASUS i5 desktop with a 30Gb SSD hard drive and a 500Gb secondary Drive. I have tried installing most of my programs on the secondary drive but a few have insisted on installing on the primary drive. I now find that I have only 2.30Gb free and this is reported as 'red' when viewed in explorer. It has also slowed the computer somewhat. Is there some way I can free up some space? Perhaps moving the User directory?
