Dear friends! My C drive has 3.89 GB capacity in which i have installed Win xp with SP2. I have not stored anyother files in c drive. Still I get only 512 MB as free space. So i checked the size of the individual folders. Documents and settings - 213 MB Program files - 680 MB Windows - 1.96 GB I cannot understand how windows folder occupies such a huge space. Can any unnecessary file be deleted to free up some space? Help please!
