[FONT=Trebuchet MS]hi.. am having 3650. been formatting my phone lotsa times for fun.. now the time's come to format the phone cos some boring files are there in the c: drive.. i've done a backup of the contacts and calendar on the pc using pcsuite.. now one thing's there.. i do not want to loose my bluetooth pairings. it's so boring to re-pair them all.. is there a system file that contains all these pairings? i tried c:\system\data\btstate.dat but that didn't work.. so anyone here knows? any help would be greatly appreciated.[/FONT]
Bluetooth Pairings...
I think you should learn how to remove the files you don't want instead of reformatting the phone.
Also, pairing are just that pairings where each memeber in the "pair" need to have a copy of the security token.
You cannot "restore" any files to the phone until it is paired. So even if you could back up the "pairing file" you can't restore it until it is paired.
