JSI Tip 10375. The COMPRESS.EXE Resource Kit utility.

The Resource Kit installs the COMPRESS.EXE utilty.

When you open a CMD.EXE window and type compress /?, you receive:


   COMPRESS \[-R\] \[-D\] \[-S\] \[ -Z | -ZX \] Source Destination
   COMPRESS -R \[-D\] \[-S\] \[ -Z | -ZX \] Source \[Destination\]

   Compresses one or more files.

Parameter List:
   -R           Rename compressed files.

   -D           Update compressed files only if out of date.

   -S           Suppress copyright information.

   -ZX          LZX compression. This is default compression.

   Source       Source file specification. Wildcards may be

                Destination may be a directory. If Source is
                multiple files and -r is not specified,
                Destination must be a directory.
