File Mask field: This is the file mask for the search/replace that is currently highlighted in the Search/Replace list (if any are present). File and directory masks can be combined to create complex file mask expressions to include files in some subdirectories while excluding those in others. The wildcards characters * and ? may be used in a manner similar to the DOS dir command, e.g., *.*;*.txt;*.doc;*.??1. More than one mask can be specified by using a semicolon separator (see above). Exclude masks use the ~ character to denote a mask NOT to search (e.g., *.*;~*.swp;~*.exe;~*.dll). To specify a ~ character as part of the file mask, use \~ to denote the literal (e.g., *.*;\~*.tmp). If you have "Search ZIP Files" turned on, the mask will be applied to files inside of ZIPs as well as ordinary files in the path specified in the path field.
