To configure RadFileExplorer to display the files in a folder you need to set its ViewPaths property. By setting DeletePaths and UploadPaths properties you can allow the upload / delete / rename / create new folder functionalities, if you do not to allow these you should not set these properties.
In order to disable the opening of the files (by double click on the item) you need to assign handler to the RadFileExplorer's OnClientFileOpen and cancel the execution of the command, e.g.:
function OnClientFileOpen(explorer, args)
args.set_cancel(true); //cancel further execution of the command
All the best,
