As I have Blackberry users accessing our server via VPNs, xp profile size is an issue to speed up logging in and out. I have noticed that users that have Blackberry Desktop Manager installed, have XP Profiles that include a Research In Motion directory under Application Data which, in one particular users case, has 10MB in it. This slows up the VPN login/ logout considerably.

Anyone know how important this stuff is/ what use it is etc or can I trash it and exclude it from the profile?

If your using BES 4.0+, and everything is synching wirelessly, you do not need the BDM installed. If you can, I would uninstall BDM which should remove the data from the profile.

Thanks. The users are syncing wirelessly so I'll see if the users can do without BDM. If not, I'll set a registry entry to exclude the folder from writing back to their roaming profile.
