I INITIALLY HAD WINDOWS 98 ON MY NEC LAPTOP BUT I UPGRADED TO XP PRO AND
EVER SINCE THE I CONSTANTLY GET LOW DISC SPACE MESSAGES AND BACKUP DISABLED
BECAUSE MEMORY SPACE IS LOW, CAN I DO ANYTHING ABOUT THIS....
ALSO, WHEN I EXPLORE MY COMPUTER THERE ARE A LOT OF FILES WITH WEIRD NAMES
CONTAINING NUMBERS, LETTERS, OR A COMBINATIOIN OF THE 2, BUT NO REAL WORDS.
THESE FILES DISPLAY IN A DIFFERENT COLOR ALSO...COULD THAT HAVE ANYTHING TO
DO WITH MY PROBLEM??? CAN I DELETE THEM?

Go to run,type:cmd
At the curser type:CHKDSK C: /R
Agree to restart,then type:EXIT Reboot computer.
Dont delete,send to my documents,create a folder,put them
in there for now,L.click the file,in sub-menu,move this
file,scroll to new folder.Do after the CHKDSK,if still
there.Asumeing the disk space is ok,open my computer,
chk the disk,R.click my computer,properties,details of
memory are listed,256mb is borderline.
