Thanks for the response - I thought I was losing my mind here
It would appear that dolphin does the same thing in its display too.
This would explain why copying all of the formats took up 200+ MB when I copied via Konqueror.
Dracolich, when I do: ls /media/cdrom I get this:
tferero@ubuntu:/$ ls /media/cdrom0
<mount point> rdiff-backup-data
The rdiff file wound up there when I was messing around with a backup utility - I still don't know what I did to cause that to happen.
But, I don't see the file on cd, even though the cd is in the drive. Comments welcome on that.
This is still new to me, so many thanks to the posters above.
