Sync reset Sync location

[Geedsen]

Got an update last week for windows phone. After that connected to the PC, And it nicely asked me to setup a sync ....but this phone was using the PC for at least a year already. And it started downloading everything again from the beginning, to another location on my PC (now the photo's went to \Pictures\Camera Roll and before it went to a directory called \Photos\From Ben's 925\Camera Roll. And as I my wife's phone connects as well to this PC, this 'From Ben's 925' makes sense.

So where can I set this location where it should sync my files too, so that I can set it back to the original location.

Thanks
