Bug Report: Improperly handling file names containing ".exe"

File names containing ".exe" in the middle of them are improperly handled.
For example, there is a file in the otherwise empty folder "\PortableApps\Example" named "This is not an .exe!!".
This would generate a menu entry "This is not an .e"
