In Windows Mobile, external storage cards are usually represented as the ‘SD Card’ or ‘Storage Card’ folder, this varies from device to device. A simple way to enumerate the external storage cards is to check all directories under the root directory that have the temporary attribute flag set.
Here’s a quick way to do so in .NETCF:
public static List<string> GetStorageCards()
var list = new List<string>();
var root = new DirectoryInfo("\");
foreach (DirectoryInfo directory in root.GetDirectories())
if (FileAttributes.Temporary == (directory.Attributes & FileAttributes.Temporary))
