Add set storage location

Components

APK Extractor is an app that allows users to extract/backup already installed apps. This proposal specifically suggests the addition of a new feature to the extraction method of the app.

Proposal

I wish to propose a feature that presents a settings menu to the user which gives the user the option of manually choosing storage location for backed up apps.
Though clearly stated the necessity of this feature can be seen from the following statements;
Smartphone storage comes in different sizes and no matter the size, for the most part, sooner or later, we get the alert: storage space is almost out.
Setting storage location which is the focus of this proposal provides a medium where the user can easily access his/her files from their file manager and can set this to either a particular folder on their SD card or folder in their device storage.
This feature is especially helpful if a specific storage location is filled and needs to be changed to allow continuous installation of apps without obstruction.

Mockups / Examples

Benefits

ApkExtractor doesn't give its users the option of storing backup apps into the external storage and that's pretty bad as it automatically stores these backup on the internal memory.
Implementing the "Set storage Location" feature would be of great help as it will give users the ability to change their file locations in event of one getting filled or used up(e.g from SD card to device storage or vice versa).
