You say "for sure". Really? Then why isn't it working as you expect?

When it comes to debugging, """assumption is the mother of all
****-ups""" [insert relevant expletive for "****"].

Assume nothing.

What is the value of 'filename'?

What are the entries in the 'files' table?

Print them out, for example:

     print("filename is", ascii(filename))

or write them into a log file and then look at them.
