I am trying to view the contents of my SD card via the File Explorer but all that is shown is a directory called 'PerSaveBackup' containing a bunch of backup files. I am not able to delete this folder (it appears no matter which card I use) and I have tried enabling/disabling the Permanent Save, Soft/Hard Bouncing etc
Does anyone know how to remove this folder?
NOTE: I am not really interested in using any backup features as I only intend to use the PDA as an in-car Satnav (with TomTom Navigator 5) so am happy to disable them completely
Thanks in advance!

(I have an O2 XDAII)
