To save a new connection file that you have just created, or to save changes to a connection file you have just modified, select Save or Save As from the File menu.
If you have modified one of the original installed files in the Program Files\EndNote\ConnectionsApplications/EndNote /Connections folder, you must use Save As to save a copy to your personal Connections folder. If you have modified a style that is already located in your personal Connections folder, you can select either Save to directly modify the file, or Save As to make a copy with the changes. For a description of where your styles are stored, see Folder Locations.
EndNote automatically saves new connection files to your personal Connections folder. You may also specify a different folder if necessary. For instructions see Folder Locations.
EndNote connection files use the file name extension of ".ENZ", as in "Medline (Ovid). ENZ".
