difference between showed used space and actual one in hard drive.?

Question

Windows shows that 100GB of C: (the only partition of my hard disk) is full. but when I get properties of all files and folders in C: the total size of files is just 46GB! Could you help me to figure out the problem!

Answer 1

dear friend i want u to know wheater u saw the properties of all files by selecting all the files at once ???
if it was the case let me tell u that when u check each and every file/folder for its size and then add them up ,u will see the difference...........,it is just b'coz when u select many folders at once and check for their size it doesn't calculate the whole file size of sub-folders and so gives up wrong or misappropriate size (u can take it as a bug or loophole or anything in the o[erayong system design)

Answer 2

Each file takes up some number of "Blocks" in the file system. So, even a 1 byte file take up a whole block. The actual difference depends on the actual blocksize (which I think depends on how big the disk is among other things).

Answer 3

No problem. hahahaha. lets assume you have 100gb of space to use. 20g should be allotted for OS and peripherals. If you reach 70 % of disk usage, you should delete/burn files to create room. To create room, delete any unused programs/applications, also burn/delete unused files. Run the diskcleanup utility as well as the defrag tool.

Answer 4

Cluster Problem!
Use PartitionMagic to resolve it in a jiffy.

If you want the lengthy method:
Reboot form a CD and (Preferably PE) and run a Disk Check (It seems your partition table is corrupt)
