Organizing Files Between Files Saved in External SD Card and Files Saved in Internal Drive For example, let's say I want to take some settings for organizing the directory target. When I take photos, I want to automatically saved directly onto the removable SD card (external drive) while apps downloaded and installed are stored in internal drive. Is it possible?
You can try Redirect File Organiser. 

The usage by dev is explained at /r/android over here.

Hope this is what you are looking for.
