for some reason i am having difficulties deleting files off of microSD card using the BB.
I can save them by downloading via Bluetooth, using USB cable or downloading from the web. I can rename or delete them when its connected with USB, but i can not delete or rename them on the 8800 itself.

sometimes it just works, but most of the time i get a pop-up "File system error". anyone experiencing the same issue?

microSD card is 1Gb SanDisk. brand new.
