Using Wildcard Characters
  A wildcard character allows you to substitute one character
  for another character or for many characters.  The wildcard
  characters include:
  -   Asterisk (*)
  -   Ellipsis (...)
  -   Percent (%)
  -   Period (.)
  For example, to search your file list for all the files that have
  a COM file type:
  1.  Click on the File Filter entry field.
  2.  Using the asterisk wildcard ( *), enter the following:
      *.COM
  3.  Click on the Apply button.
  In this example, the asterisk character is used as a substitute
  for all the file names.  FileView searches for all the files whose
  file type is COM. These files are then displayed in the file list.
