Backup needs one more option

I use PortableApps to install apps on my hard drive (C:). I wanted to backup my installed apps, so I tried to use the Complete option since the App Data and Documents option do not include the apps themselves.

This did not work. The backup hung and I had to use the task manager to kill it. The Complete option tried to backup my entire C drive, not just the C:\Portable directory. Apparently it hung waiting to open a file that Windows would not let it open.
