What are the default destination options?

[Zorat]

I tried to look in help, and also on here. I just wanted to see what they do.

None
Auto
SemiAuto
Custom

Does anyone have an explanation, or can point me where to look?

None - You choose a folder every time.

Auto - A subfolder named for the disc is made under a VIDEO subfolder on the drive with the most free space.

SemiAuto - A subfolder named for the disc is made under the drive and folder you specify in the options.

Custom - The drive and folder you specify in the options is used.
