I tried to reproduce the described issue with the latest version of RadControls (2012.3.1205) but to no avail. Which is the version of the controls used in your application?
Basically the default RadFileExplorer's content provider uses the
methods of the
class in order to get the directories/files. If these methods returns the files/folders, then RadFileExplorer should work. as well. You can test the methods by using this test code:
sender, EventArgs e)
physicalPathToFolder = Server.MapPath(
System.IO.DirectoryInfo dirInfo =
System.IO.FileInfo files = dirInfo.GetFiles(
System.IO.DirectoryInfo directories = dirInfo.GetDirectories();
Another thing I could think of is some kind of permission restrictions. You could see how to test them in the following help article: Troubleshooting
Additionally, if non of the above helps in solving the case, I would suggest you to implement a custom FileBrowserContentProvider for directly accessing physical folders. You could use the one from this KB article: Use RadFileExplorer with physical and shared folder's paths.
