Here's a simple idea which I find is severely lacking...
We need a simple XBE utility which when launched will look at a configuration.xml file and then COPY the entire directory structure from one directory listed in the XML (from a DVD disk for instance) to a target directory on the Xbox HDD, ideally with the option of skipping certain files if they exist (selectable in the XML file), or only updating files of a give age.
So, now you wonder, what's the use of this...
Do you have a friend, relative or acquaintance, who is a complete Xbox IDIOT?
Ever need to send them an update in the mail for something on their machine?
Get the picture?
You can burn a DVD with all the required software (say for instance new files for the XBMM Karaoke player) and have this little application automatically boot up and start copying the files.
Better still would be if it could detect if the files exist and are up to date, so it can skip the update altogether if so.
Have someone who trashed their dash and they don't know how to restore it?
Need to send someone a copy of the latest XBMC?
Get the picture?
It's a simple but eminently useful tool.
