For various reasons, I am going to be performing a clean install of Tiger on my PowerBook. I'm still somewhat new to the Mac world, and as such, I've never had to transfer files and settings to a new OS X installation. I definetely want to hold onto all my emails and such. For this, what files should I back up? How about stuff like iCal and iPhoto? Do I just back up my iPhoto Library folder? I'm not sure what to do with iCal.
If anyone has done a clean install, and had to back up these types of files, can you tell me what files you backed up? Not only do I want to be sure that I don't forget to back up files for certain programs, but I also want to be sure that the files I do back up are enough to provide my new installation with all the necessary information.
Any help is most appreciated
