b.  Decompressing Data From WOA05

Copy data files to selected folder.
Use gzip to decompress selected files or a directory and all subdirectories with one command.

gzip has a limited help menu accessible with the -h option (i.e., gzip -h).

To decompress a single file:

gzip -nd <filename>

To decompress the contents of a directory and all subdirectories:

gzip -dr <directoryname>

If an older version of gzip is used, the -n option is required in order to preserve the correct file names.
