C:\WINDOWS>HELP COMPACT
Displays or alters the compression of files on NTFS partitions.

COMPACT [/C | /U] [/S[:dir]] [/A] [/I] [/F] [/Q] [filename [...]]

 /C        Compresses the specified files.  Directories will be marked
           so that files added afterward will be compressed.
 /U        Uncompresses the specified files.  Directories will be marked
           so that files added afterward will not be compressed.
 /S        Performs the specified operation on files in the given
           directory and all subdirectories.  Default "dir" is the
           current directory.
 /A        Displays files with the hidden or system attributes.  These
           files are omitted by default.
 /I        Continues performing the specified operation even after errors
           have occurred.  By default, COMPACT stops when an error is
           encountered.
 /F        Forces the compress operation on all specified files, even
           those which are already compressed.  Already-compressed files
           are skipped by default.
 /Q        Reports only the most essential information.
 filename  Specifies a pattern, file, or directory.

 Used without parameters, COMPACT displays the compression state of
 the current directory and any files it contains. You may use multiple
 filenames and wildcards.  You must put spaces between multiple
 parameters.
