Delete assets in a "Resource" folder from iOS install

Question: Is it possible to programmatically delete assets included in a "Resources" folder on iOS?

Background: Our Unity Project, which is geared towards iOS, has many asset files placed in a Resources folder. The first time the app is launched, these files are loaded into memory then saved back onto disk in a new location (essentially creating a duplicate copy). Since the majority of these assets are image files, this effectively doubles the install footprint of our app. Is it possible to delete the original file from the Resources folder? As a work around, could we at least null out the data, so the file size becomes negligible?

To preempt the question of, "Why are you bothering to re-save your assets to a different file/directory?" We do this so that we can alter the asset files during the lifecycle of the app (for example, art gets updated, therefore we want to overwrite a few of the existing art files).

Thanks for your help!

 

No, the Resources datafile cannot be changed. Sounds like you want to use AssetBundles.
