 The filter command allows you to control what files you see
 in the Left or Right file panels.

 There are three options:

        +-------- Filter ---------+
        | Select files to display |
        |   (.) All files         |
        |   ( ) Executable files  |   .--- .com, .exe, and
        |   ( ) Custom:           |        .bat files
        |                         |
        --------------------------|
        |   [ Ok ]   [ Cancel ]   |
        +-------------------------+

     .  All files is the normal case.
     .  Executable files shows only program and batch files.
     .  Custom: allows you to supply a DOS wildcard pattern to
        select which files you view.

DOS Wildcard Characters
-----------------------
 DOS file names have two parts: the name (which can be up to 8
 characters) and the extension (which can be up to 3
 characters) with a period in between.  For example,
 "filename.ext".

    *   Match any characters for the rest of the name or
        extension.  "a*" will match "a", "ab", and "abc", as
        well as many others.  '*' applies just to one part of
        the file name, so "a*" will not match "ab.c".  Use
        "a*.*" to find all files that start with 'a' and have
        any extension.  (Note: "*a" will match any name, and
        not just names with an `a' at the end as you might
        expect.)

    ?   Match one character.  So "a?" will match "a", "ab",
        "ac", etc.  "????" will match any name with up to four
        characters.
