How to decompress files

I bought the My Passport to serve as a backup device.  Now that I’m ready to restore the files to a new computer, the browse can’t find any, they are all in a compressed state. No instructions on how to decompress them.

Hello,

What backup software did you use? Western Digital backup software does not compress the files. In order to retrieve these files, you will have to use the same backup software you have used in order to backup.
