If you ONLY delete the character in the Characters library, no, the obj file will still be there. All the character deletes is the cr2 and rsr stuff :) Make a backup if you can of all your purchased things, archive the hell out of stuff. CD's, Zip Drives, even Zip Files spanning several disks like Winzip can make. I find myself going back to my archives of old things very often. I thank the day I bought a CD burner.
