Commands To Decompress Files On A Compresses Hard Drive

You can uncompress all the files on a Hard Drive from the command line on a drive that has all files compressed or that had selected files compresses. Open a command prompt and from the root of the drive (to decompress all files on the drive) or the root of the folder you want to decompress type the following.
