My two penneth
I think there are arguments for both sides - as always - I'm sat on the fence
For those that want to go out and create their own ADF management system - great Aminet.
For the lazy buggers like me that like to have it done for them - thanks AmigaKit.
I use EasyADF and ADFBlitzer.
ADFBlitzer won't handle anything else but ADFs - which it's very good at.
EasyADF will do ADFs and Archives. Saves messing with different programs.
