For each application we examine, we will provide a package name and files of interest. All apps store their data in the /data/data or /data/user_de/0 (newer devices) directory by default; apps can also use the SD card if they ask for this permission when the app is installed. The package name is the name of the directory for the application in one of these directories. The paths in the Files of interest section are from the root of the package name. Paths to data on the SD card are shown beginning with /sdcard. Do not expect to find data paths beginning with /sdcard in the /data/data or /data/user_de/0 directory of the application!

We will begin by looking at some of Google's applications, because these are pre-installed on the majority of devices (though they do not have to be). Then we will look at third-party applications that can be found on Google Play.
