Better File Select is a shell extension for the Windows Explorer, which allows users to quickly select multiple files based on a range of criteria. The simplest selection method is through partial file name matches, ie. "select all files which contain .gif". A more powerful method is to use wildcards known to many users through UNIX and DOS. Select all files which match 'image*.gif'" will match all files which start with "image" and end in ".gif". The most powerful method available is to use regular expression pattern matching which is available on powerful unix commands.
