Xbox extender

[Trainman611]

Can my xbox extender be used to access my other computers and do file sharing with vista?

It can be used to stream media from any computer running XP, vista, windows 7 or other OS with a suitably configured DLNA client installed.

As far as i know, you cannot use your xbox to copy files between computers or access other files apart from media being shared by the host computer.
