вопрос по iTunes ...

привет, погугли junction.exe
если будут вопросы - спрашивай, но смогу ответить только завтра вечером.

Close iTunes
Download junction.exe from Microsoft and in Windows 7, place it in the C:\Windows folder.
Remove the folder "C:\Users\%USERNAME%\AppData\Roaming\Apple Computer\MobileSync" and all sub folders. (so there is no MobileSync folder anymore)
Create a new forder structure D:\Программы\iPhone\backup
In Windows 7, open a command promt as an administrator. Now execute the following line....
---------------------------
junction.exe "C:\Users\%USERNAME%\AppData\Roaming\Apple Computer\MobileSync" "D:\Программы\iPhone\backup\MobileSync" -s
---------------------------
The command will have created an folder (looking like a shortcut) in the origional location on the C:\ drive.
Now connect your Apple device of choice and watch the folder "D:\Backup\MobileSync" get filled up with stuff.
