FileSystem: need support for Apps root directory (parent of /files)

[hschindler]

Feature Request

Plugin

• FileSystem

Description

I need access to the apps root directory. Actually the DATA-directory give access to '/data/user/0/app-id/files.
I need access to the parent directory of files: '/data/user/0/app-id/'. Because my sqlite database is stored under '/data/user/0/app-id/databases/sqlite.db'. And I would like to export this db.
The cordova-plugin-file uses the code 'context.getFilesDir().getParentFile()' to access this directory.

Platform(s)

• Android

Preferred Solution

The cordova-plugin-file uses the code 'context.getFilesDir().getParentFile()' to access this directory.
Add a new enum value 'DATA_ROOT' or change existing 'DATA' to 'DATA_FILES' and use 'DATA' for root access.

See: https://capacitorjs.com/docs/apis/filesystem#understanding-directories-and-files
the Filesystem API supports using full file:// paths, or reading content:// files on Android which should start at ROOT Level.
