Can anyone tell me what type of files are backed up on the N800 when the 'other files' box is checked please. Reason I'm asking is that when running the facility my usual backup size of 33MB has suddenly shrunk to 5 MB for no apparant reason! Compared with the last backup content, the device is not backing up 'other files' although the box is checked hence the reduction in file size backed up. I don't recall deleting much since the last backup, but now I afraid I'm missing important files each time I run backup now. I did try to run a backup with only the 'other files' box ticked, but got the message ' No data to backup. I am getting worried! Please help... Thanks
