I am having problem to get the root folder name of a mobile (working with device (Nokia-5800)). The value I am getting is "null".

The same code when run on the emulator (Nokia-6350), I am getting correct root folder (/root1/) which is under "/DefaultColorPhone/filesystem/".

Please let me know, how can i get the root folder name for any mobile device in a J2ME Midlet application.

The code i tried and i got the value as null is shown below:

Enumeration roots = FileSystemRegistry.listRoots();
String rootFolderName = (String)roots.nextElement();
Alert splashScreen = null;

if (rootFolderName != null){
splashScreen = new Alert(null, "Root folder is not null: "+rootFolderName, null, AlertType.INFO);

splashScreen = new Alert(null, "Root folder not found", null, AlertType.INFO);

The output i am getting for this is Alert Screen Mentioning "Root Folder not found".

Is there some other way where we can get the root folder name? Please assist....

Thanks and Regards,
