CCMPRS is a command-line file compression utility for Windows NT.  It allows
you to select files for NTFS file compression based on file name (with wild-
cards), minimum file size, and/or a minimum compression ratio.  You can also
specify file extensions of files to be ignored.

The command line format is:

  ccmprs filespec [options]

where filespec is the path and filename (wildcards allowed) of the
file(s) to be examined.  The options are:

  -s  : Examine files in subdirectories as well as the specified directory.
  -d  : Decompress any compressed files encountered that do not meet the
        specified conditions for compression.
  -t# : Compress file only if resulting file size is # percent or less of
        the uncompressed size.  If this option is not specified, the default
        is 75 percent.
  -m# : Compress file only if its uncompressed size is at least # bytes.  If
        this option is not specified, the default is 0.
  -xa[,b[,c...]] : Ignore files with the specified extension(s).  For example,
        -xzip,gif would ignore ZIP and GIF files.
  -q  : Operate quietly, with no status info displayed.

For example, the command:

ccmprs d:\stuff\*.* -xzip,gif -s -t66 -m10000

would compress each file in directory d:\stuff and its subdirectories, but only
if the file is at least 10,000 bytes long, and would compress to 66% or less of
its length.  ZIP and GIF files would be skipped.

I developed and tested this program under Windows NT 3.51, service pack 3.
I don't know how well it will work under 3.5 or 4.0 beta.

The included .MAK file is in Visual C++ 4.0 format.  Since this is a simple
console app, it shouldn't be too difficult compiling it with other 32-bit
compilers.
