Compressed Files
UNIX compressed files (.Z) are expanded on the fly. If you have a compressed image, say bigimage.rgb.Z, it is treated as the corresponding uncompressed file (bigimage.rgb).
The standard UNIX uncompress utility must be available on the system.
"gzip'ed" files (.gz) are also expanded on the fly. If you have a compressed image, say bigimage.rgb.gz,
it is treated as the corresponding uncompressed file (bigimage.rgb).
The required gunzip filter must be available on the system.
gunzip is part of the free gzip package available from many sources;
check www.gnu.org for the nearest download location.
gunzip is automatically installed with the Windows version of EasyCopy.
"zip" archives (.zip) are partly expanded. If gunzip is installed EasyCopy will
read the first file in a zip-archive.
