Will be nicer a message explaining that the selected UMD folder is empty.

Fixed in r2777. Thank you for reporting!

Thanks to you for fix it!

RE: Minor issue: Empty UMD folder message does not exist. - montcer9012 - 10-16-2012

Found a related (But awkward to get by accident) issue, this time is when the selected UMD folder is protected by Windows. E.g: "C:\", "C:\Windows", etc. Even starting JPCSP like administrator (Since r2772) it can't access those protected folders.
But, for being so tricky this one i guess the solution is closed to a message like "This folder does not contain a valid .iso nor .cso image."; i don't know, is up to you gid!
