Basically the only way to do this is to move are your large files, ie; photos, videos, music and pdf’s, to another source that you already have. Other sources would be blank DVD’s, CD’s, Flash Drives, or other external hard drives. If you have media that you don’t need or want, you can can just go in and delete them. To look for these files, Go to ‘find files’ on your start-up menu and type; .mp3, .jpeg, .tif, .wma. These will be some of the more common large files on your computer.
