Transfering Library

Is there a way to tranfer the GLobal Librar from version 3.5 to version 4.5?

Well, either leave your 3.5 library where it is, or move the whole library into your 4.5 library folder on your Hard-drive,

Open Studio and the Library window / right-click the Global-Library-Folder and from the
contextual window choose Open Library / go to your 3.5 library and open (import) the
“.tbc” file. This should be the only one highlighted.
If you have more folders, open one after the other and import.

This should import all your templates, including sub-catalogs (if you have those).

Save Global Library…
