While most applications have directories in the USERDATA/data directory, some store unique data (file attachments, video, databases, and more) on the SD card or the internal USERDATA/media directory. We cannot stress how important it is to thoroughly search the entire device for all remnants of application data. As you saw with the Zedge example, the data can exist anywhere.
The SD card (/mnt or NONAME) contains multiple directories that may be different on each device you examine. Look carefully and dive into any directory that contains application data of interest. Be ready to parse a lot of this data manually. Directories that are commonly found here and that should be examined include:
• Android
• Download
• Media
• <Application directory>
The USERDATA/media/0 directory is essentially an SD card that is stored internally on the device. Directories that are commonly found here and that should be examined include:
• Android
• DCIM
• Download
• Pictures
• * - Yep, all of the other directories that contain the data you are most likely trying to piece to that database of interest.
