Hey so I just updated to 4.0 and am wondering should I delete 3.0? I know its a large program and just want to make sure deleting it wont mess up my books or the new OS. Thanks for any help!
Kurt, welcome to the forums and to logos 4.
No it won't hurt anything to delete it. If you have note files, highlighting, prayer lists, or items mentioned here: http://wiki.logos.com/Importing_from_LDLS3 you'll want to import them into L4 first. If you had Personal Books (created by Personal Book Builder) those won't transfer. Your only recourse is to rebuild them in L4 if you have the original source files (not the compiled books) or keep L3 to use them.
