Hi,
The RAM disk will always show as 100% full - it doesn't take up any more space that it needs, therefore there's never any free space reported.
It's normal for a full install of Workbench to use part of the RAM disk for storing preferences, etc. However, it's possible to create a cut-down startup disk to minimise this.
How are you transferring the ADFs to your A600? Via PC disk, or a serial cable or some other method?
Do you have a cheapo CompactFlash to PCMCIA adaptor plus an old CompactFlash card? This would help with transfers as you don't have a hard drive.
