I found this trick on another forum.

hey ppl, U want to your pc can read resource, private, and sys folder? Just do this:
-create virtual device (folder shortcut) with mapdrive app by FCA00000. thanks to FCA, example R:\resource, P:\private, S:\sys.
-now map this drive(starting application mapdrive), Note! That U need to turn on CapsOff before mapping drive.
-now connect your phone using pcsuite mode and from computer (mycomputer) open Nokia Phone Browser. do not open drive with phones symbol indicator or from PCSuite menu.
-now U will see 7 (or many) drives into your nokias phone browser and U can now copy, move, paste any files U need.
