Yes, this is an obvious easy way to get such collections over to an Amiga with a CD drive. However for convinience being able to copy the complete 4GB+ KGWHD set of game packs onto the HD in one go on the PC is quicker. I do however add the update packs to the already setup HD in my A1200 by burning the update packs to a CD-R and copying them over that way.

However that still doesn't solve the issue of copying the files for any version of ClassicWB over to the Amiga, or the SFS and IDEFix packages that are larger than a floppy disk. And the think is you need IDEFix installed along with your OS setup of choice before you can access the CD drive. There are ways but not are as easy or as quick as the PC and emulator route.
