My OS is xp home sp2. Connected to my pc is an External 40 GB USB hard drive. This shows as having a total capacity of 37.3GB with a Free space of 37.2GB and used space of 65.6MB. However, if I double click on the F drive in "My Computer" it shows as empty. So what is the 65.6MB shown as used space. Any ideas please.
No - Windows Explorer - it's in the menus as Explorer, or right-click on Start and select it from the context menu, or ad woodchip suggests. Then when it opens go to Tools - Folder Options - View - and look for the appropriate boxes - View Hidden Files and Folders and Hide Protected Opereating system Files .
Don't forget to change them back later if you wish to (safest).
