Before you run this command, you must shut down the subsystem that owns the file.

If a file has more than 10 percent of unused space, you can compress the file to save disk space.

1. Find the percentage of unused space in a file. See List the header and index.

2. In a command line window, change to the PI\adm directory

3. Type:

   pidiag -fbcpath [-header]

   where path is the complete path of the file.

   Use the -header option to list only the header.
