Easily read/write files on Phones/Tablets that connect to your PC via USB.

Deal easily with any external drive, even if you can't find it in the available drives (DriveInfo.GetDrives)

As soon as you plug in a Portable Drive (Phone/Tablet), it will show up in the available drives, here:

drive_root.inst.drives

Enumerate all the pictures you've taken (a0 - first android drive)

Console.WriteLine(
  string.Join(",",drive_root.inst.parse_folder("[a0]:/*/dcim/camera").files.Select(f => f.name)));

Copy to HDD, the last 100 photos you took

// a0 - the first connected Android device
static void copy_to_hdd() {
    var files = drive_root.inst.parse_folder("[a0]:/*/dcim/camera")
        .files.OrderBy(f => f.last_write_time).ToList();
    if (files.Count > 100) 
        files = files.GetRange(files.Count - 100, 100);
    foreach (var f in files) 
        f.copy_sync("c:/my_camera_files");
}

Show all Albums you created on your Android Phone

var dcim = drive_root.inst.parse_folder("[a0]:/*/dcim");
foreach (var f in dcim.child_folders)
    Console.WriteLine(f.full_path);

Copy the last taken photo, to its parent folder

var camera = drive_root.inst.parse_folder("[a0]:/phone/dcim/camera");
var last_file = camera.files.OrderBy(f => -f.last_write_time.Ticks).First();
last_file.copy_sync(camera.parent.full_path);

If you want more info, I've written a rather large article on codeproject
