I have some +RW disks on which I made some recordings. When finished with the recordings, I put the disk back in the recorder and had it erase it. I then looked at the disk using the drive in my computer. There are sub folders and file still on it. when I look at the properties of the disk, it shows 3.46 GB as being used but, when I add up the size of the stuff in the 2 sub folders, I get about 1.07 MB. I am attaching 3 screen shots of what I'm seeing. My question is, when the disk reports to the recorder that 2/3 of it being used, does the recorder compress what I'm trying to record into the 1/3 that's free? If it's not clear what I'm asking please give me a chance to further explain.
