well to be honist I don't know how the hell you could use 250GB it is a hell of a lot
of data put it this way I have all my files photos music and movies and software
total of 15,900.50 files and only used 99.9GB of it must be a problem.
do you use Ccleaner?
if so there is a function on there called disk wipe that saves the disk space not a
good idear but can be rectifed.
use this http://www.file.net/freeware/top100files.exe
to find out what is taken the space top 100 files most common is page file.sys as it
uses 4 gig or more depending on your settings.
