My blackberry is french so not sure of the name of the files.
On your BB:
- Go to parameters / Storage and acess
- here you have to enable Wifi access
- Change the wifi password
- Then click on network information to get your domain name and user name.
Then connect with USB your BB to the computer.
On the computer:
- Clic on your file directory
- Then clic on "Parcourir le réseau" in french so maybe "explore the network" ?
- Explore the different directories (there's one named "windows network" ?)
- Find your Blackberry directory and clic on it, a pop up will ask you your User name, Domain name and password you found and changed on your BB.
Then it works for me.
