Create/Delete File for Product?

[Bilderback]

"The normal process with a Product which includes files"
meaning a Product / Mod which has custom files in its package.(php,xml,etc)
I too, have found myself uninstalling a Mod due to it becoming outdated, unsupported
or just conflicting with new vbulletin or Mod updates.
Then I need to figure out which files I had uploaded associated with that particular Mod.
If the Mod has hit the graveyard, you can no longer download it for reference.
And if you do not have a local copy for reference, it boils down to scanning the code
to see how the script runs and what it calls.
Mainly the reasoning behind my questions.
