Disk Space is something how much you have is always less. New computers does come with hard disks which has boat load of disk space, but many people may have older computer where free disk space is not what it used to be. One option would be to upgrade or buy a new hard drive, but what if you're not that tech savvy.
Another option in Windows XP and Windows Vista is to compress the entire folder, so that every file that is stored on that folder is automatically compressed when saved and decompressed when opened. The beauty of this thing is that you don't need to compress or decompress the files, it is done automatically by Windows. You wouldn't even notice it. It's like working with any other normal folder.
Note: Before you try to compress a folder, make sure that folder is on NTFS file format.
