<p class="p_Normal">Simple file masks will affect any files or folders whose parent folder is included.  The base folder is always included.  All folders which contain included files are also included.</p>
<p class="p_Normal">To exclude rather than include the specified items, add a minus sign (-) in front of a file mask in the <span class="f_Command">Filters</span> edit.  In the File Filters dialog, place the file mask in the Exclude edit rather than using the minus sign.</p>
<p class="p_Normal">If the last character in the file mask is a period (.) then ? and * wildcards do not match periods to allow filtering of files that don't have an extension.</p>
