I did the cleansing suggested. And saw the removal of a number of files. I then found another post by #Ashtree which called for the removal of yet another divx file. I did so, but found the file to be non-existent.
In order to properly 'see' these files - and any other like them - you need to open the Finder and set your VIEW to-> Columns; then set the ARRANGE to-> Date Modified. This allows you to see different venues of existing DivX or divx files.
