This is a small tool to inventory external data devices. It allows the user to manage his external devices (e.g. USB Flash Drives) in one list. A backup is possible with the CSV export.
The CSV export writes to the folder: /mnt/sdcard/Android/data/de.dinardo.android.device.manager/files/devices_n.csv
The export format changed slightly, so files exported prior Version 1.1.0 cannot be imported.
