I have a problem ever since i installed windows xp professional on my computer. The thing is, the free disk space on my hard disk is continously decreasing, even though i am not installing any programs or doing anything to increase the space taken up. For instance, 2 days back when i booted my computer, the free space on c:\ was around 500 mb, whereas yesterday it was below 400 mb, and today is around 300 mb. The problem seems confined to c:\ only. The space on d:\ is more or less constant. My hard disk is only 10 gb, with 2 partitions: c:\ and d:\. The space is equally distributed at 5 GB for each drive. Windows XP is installed on c:\. The problem has appeared only since i installed XP. The installation was a fresh install, as i had tried and failed to install XP using the upgrade option earlier. I had windows ME earlier, and there was no such problem with it. The virtual memory management options have not been touched by me, so i assume they are the defaults. Can anyone tell me how i can modify them if necessary? Also, is there anything else i can try? does anyone know what the probem could be? Also, i am reasonably certain that i dont have any spyware installed..but can anyone tell me how to weed it out in case? i have zone alarm pro installed as well as norton antvirus 2003 with the latest virus definitions. The temporary internet files have also not increased dramatically enough to cause almost a 200 mb loss in a couple of days. In any case, the limit specified for them is 100 mb, of which it is currently at around 80 mb. What i feel is, windows xp is creating some files by itself that rapidly gobble up the space without getting deleted. Does anyone have any idea what the files could be? The disk capacity on C:\ is only 5 gb in all, so you can imagine the problem caused by the rapidly dissappearing space.. The computer configuration is: Pentium III 550 MHz Intel 810 Motherboard 10 GB hard disk 128 MB SD RAM Windows XP pro fresh install over Wndows Millenium edition. Service Packs 1 and 2 for Win XP are NOT installed. Also, i prefer to solve the issue without installng them.
