Notes Android Directory Structure

This post is about the native directory folder structure of Android. This means for a phone, tablet, phablet, smartphone, etc which runs a modern Android OS (current latest is 4.4), their internal directory folder structure is the topic of this post.

The way to see the directory is to use various apps such as "File Manager", "File Commander" or other similar applications. This post aims to describe the common folder structure so it is easy to find things when we know it.

When new apps are installed, many would have their own folder created under the top level directory. Besides apps, there will be an existing number of folders following a new installation of Android.


The directory / folder structure is like:

Alarms
amazon ------------- your own app
Android
-- data
-- obb
..........
burstlyImageCache
burstlyVideoCache
DCIM --------------- images taken with camera usually goes here by default
-- .thumbnails
-- 100ANDRO
-- Camera
Download ----------- downloaded files usually go here by default
kindle ------------- your own app
Music
Movies
Notifications
Pictures
Podcasts
Ringtones
whatsapp------------- your own app

Examples of a few apps shown are: amazon, kindle, whatsapp

One obvious point is that there are thousands of apps out there. The list below deliberately contains only a few apps per category. The goal is to list the top apps only, so readers don't need to face with hundreds of apps for the same functionality, especially many of the available apps are questionable.

For reference, the other older sites are:
