Unable to delete folders, only single file

[GoogleCodeExporter]

I've written some code that creates a folder and three file under it.

From explorer i'm able to delete the files, but there is no way to delete the
folder, because the 'minus' icon is disabled (grayed) after clicking on a
folder.

The folder is under sdcard, i've permission to write (from the app), so i don't
thing there is a permission problem.
