i have an ntfs c drive partition. My computer did closed due to power failure inappropriately due to power failure in the last fewdays. On selecting all of the contents of c drive and seeing its size it shows a total size of 4.03 GB .But on my computer menu it shows 50mb free out of 4.98 GB .Why a decrepancy of around .9 gb?

in addition to jamietoners post - there will a lot of other hidden files/system files. Also, if you use hibernation, hiberfil.sys will be the a file the size of your RAM.
Unhide files to view - the settings can be changed from windows explorer>tools>folder options>view,  under hidden files and folders.

You also need to include syatem restore.
That does eat up disk space.

The default for system restore is 10% which means about .5 gb of disk in your case.

Depending upon how much RAM you have ,your page file can be up to 1.5 the amount of memory in the system.

Go into the drive in Windows Explorer, select ALL files and get the properties for them. You will see 2 numbers listed, size and size on disk.

Odds are you have quite a few small files that are not fully using their clusters and are therefore wasting a lot of space in unused clusters. Not a great deal you can do about it without formatting though.
