This is a File Listing Tool that is entirely compatible to all file-types. Note: This is useful for copying lists of files (with their extensions) to clipboard so that you can fill-in 'INCLUDE' sections. I hope this helps...
One thing that may apply, you may need to set your folder options so that file extensions are listed for known file-types. Other than this, there is an in-built help text, just type 'HELP'.
