Somski released a new version of Xbox 360 ISO Extract:

This program allowes you to extract multiple xbox360 isos based on exiso(info).
+ you can scan recursively through a directory and pick every iso (every iso must be in a seperate dir)
+ each iso will be extracted to the target_dir\where_the_iso_is_located_in
+ skips extracting if target_dir already has the directory
+ "remove iso afterwards" functionality (be careful! maybe some bugs)
+ statusbar and log window
+ automatically deletes the $SystemUpdate directory (since it's not needed)

What's new/fixed:
+ order of the queue is changeable now
+ last iso and extraction dir are saved now
+ scans the iso directory on change and startup (needs a bit longer to load)
* some error handling added
