Android doesn't even let you access your files. It has famously blocked acess to the subfolders of /Android/data/ - every app has a subfolder there where it stores files. And you can not visit these subfolders since Android 11.

A buggy app accumulates gigabytes (literaly, i am not exagregating) of temp files there, but i cant visit the folder to delete them.

Google explains that "it's for you safety".

I have to call it with the strong word "idiotic".

There are apps now where storing files in a shared, accessible folder is a payed option.

Not only that is outrageous, I belive that violates the existing "right of access" laws like GDPR. I am condidering even submitting Subject Access Request to Google about my /Android/data/ subdirectories.

No, I dont want to clear storage - there is data I downloaded into the app and work with that I dont want to lose. But the app also accumulates some temp files there.

without access - how do you know the files are temp files?

I used to delete them on old Android version.
