Solution to the ADDT error message
Just go to the user configuration folder: Configuration/Severbehaviors/php_mySQL/DigitalFilePro/Delete File.htm
and rename it to something like: Delete Files.htm
Then open it and change the html title tag to <TITLE>Delete Files</TITLE> instead of <TITLE>Delete File</TITLE>
Next go to the file in the same folder: Delete File.edml
Open it in notepad and update the reference to Delete File.htm and update it to the new file name.
