First of all, please turn *off* the CAPS LOCK on your keyboard. Using all uppercase is considered shouting and is generally considered to be rude.
The OneCare backup compresses the files to save space on the destination, as do most other backup programs. To access the backed up data, you then need to use the Restore feature from OneCare - which will put the restored data back to the original locations. If you want to see your files in their original form, you don't want a backup, you want a copy. You can manually copy the files using Windows Explorer or you can have a look at a program called SyncToy, which is a free utility offered by Microsoft that allows you to keep files and folders synchronized between locations.
