Create/Delete File for Product?

[Bilderback]

Hi, I am beginning to dive into the Product creation and was trying to find the simplest way
to manage a Product for the admin through the Install/Uninstall process.
The normal process with a Product which includes files is to upload via FTP and import product.xml
Is it possible to completely avoid file uploads and simply write PHP to create & delete files
or will I run into folder permission problems and/or errors?
Or is this possible through .xml or even a practical approach?
I see some forum owners uninstall Products and such and forget to remove relevant files.

Example:
Import product.xml which creates any needed files (product.php,bitfields.xml,cpnav.xml,etc)
And at Uninstall, all these create files would be deleted.

Just curious - thanks

on a product, there is no file upload, you create and manage it thru the admincp only...

"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I too, have found myself uninstalling a Mod due to it becoming outdated, unsupported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.
