META: my reply including the list but was bounced because my default email

I'd suggest these files are the Model part of MVC and you should have a
Class that you use to interact with files. This Class is independent of you
Catalyst App and should be able to run in it's own right. Page 135 of the
book discussing Database model because that's the common model but there
are model class for working with files[1]. There are several references in
the book to testing. Testing, along with software versioning are part of
the tool-set you'll want to become familiar with if your going to be
writing software. You could take a look at the advent calendar articles
[2], they are not that up-to-date but useful none the less I'd say.

Using a database would adios your permissions problems too. If you just
want to sort out permissions problems, you could have the files/directories
owned by the same user that runs you web server or do something fancy with

I want to caution you, in the nicest possible way. Writing software
requires a number of skills and a lot of research and learning. You can't
avoid the latter. What may seem like a lot of unnecessary aggravation
(testing and version control) have come about because it's no fun fixing
problems after the event.

You could also look at Dancer2 [3] as that be good fit too.
Good luck,
