1- You are just awesome for answering this fast

2- if i can't access the app folders i can't install and load scripts which are in the "downloads" folder in my phone (i unziped the script, have now 3 folders "images" "scripts" "sounds" that i can't put in the right place cause of no admin/root). If i try downloading scripts from the app and not from navigator i get no summary of what the scripts are except tags which isn't enough imho. (while testing i had only 2 ads this time).
It may be a bad idea, but, as i'm totally ok to support server costs by watching ads, can't you set no quota but a number of ads depending of the file/script size, except maybe for the biggest files? (no idea if it's even feasable

)
Maybe you can add a "load-from-zip" or a "load/copy unzipped folders-to-app" option in app.
This would spare a nice amount of bandwith too (both sides ^^) as i already have some scripts that i could transfer from pc.
Kind regards

PS: i add a screenshot of the caustic 3 public storage folders on my phone, i could totally transfer the contant of the scripts folders to those, dunno if it's helping you tho. On the caustic site there's only this words "All files are stored on the user-accessible storage, and users can supply their own WAV files for use (...)"
