Hey, Bubba!
Two other ways...
I'm using the editor marked as being from Jun 23 2010, and when I am adding media to my executable, I can select multiple files at one time. So a "select all" would get all your files in.
Or, you can edit your project's .dbpro file and under
; **** External Files Information ****
; **** Media ****
you can add in as many files as you like.
But, as said above, the files will have to be unpacked every time you run the program, so an installer might be your best bet.
If you don't want the user to have access to your .mp3 files, then you might consider using memblocks and memblock files to store and retrieve your files.
