Where is content://cz.mobilesoft.appblock.fileprovider/cache/blank.html stored?
This URI links to a local cache directory in your Android file system. Specifically, it is stored within the AppBlock application’s sandboxed environment. It’s not accessible to other apps or users without permission. The file acts as a placeholder rather than hosting any real content.
