Hard drive space is missing?

by banjobarry / January 24, 2008 10:19 AM PST

My friend is running Windows XP Pro on his laptop. His C disk, the only partition showing in My Computer is a total of 30GB.

He is running out of hard drive space for no apparent reason. I ran a scan with JDiskReport showing his largest files and how much space is being used on the C: drive. Only about 10GB of files were being accounted for, which means that around 10GB of space has just disappeared.

What could explain the missing hard drive space? Any suggestions or ideas would be greatly appreciated.

Thank you,
~ Banjobarry

would be System Restore is allocated its maximum amount of disk space. You can check this by holding down the Windows logo key and hitting the Pause/Break key. Select System Restore tab, settings, and verify the amount of disk space allotted. This can be quite a few Gigs.

In addition to the restore points ...

how large is his Internet cache set and how full is his "recycle bin"?

Additionally, if he has some type of system utilitys that includes an "Undelete" utility, that utility often protects a certain percentage of deleted files from overwrite by "hiding" the space they occupy from the file system - if your friend has such an undelete utility have him purge its cache.

And one more item that may not have been noted by JDisk Report is the swap file.

Meet the drop-resistant Moto Z2 Force

The Moto Z2 Force is really thin, with a fast processor and great battery life. It can survive drops without shattering.
