How to list additional external storage folders (mount points)?
<p>By default, "external" storage on Android is presented as /sdcard folder. On some devices it's not SD card but internal memory.</p>

<p>Some devices allow attachment of additional SD card, or in case of Asus Transformer, also additional 2 USB flash discs.</p>

<p>Such added memory drive appears as some folder, which location depends on device manufacturer. On some devices it's inside /sdcard folder, on others it's elsewhere in other folder.</p>

<p>Now <strong>my question</strong> is, if there's some function to list all possible external storages besides standard /sdcard folder.</p>
