To save a new style that you have just created, or to save changes to a style 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\StylesApplications/EndNote /Styles folder, you must use Save As to save a copy to your personal Styles folder. If you have modified a style that is already located in your personal Styles 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 Preferences.
If you close a Style window before saving a style, EndNote prompts you to save or discard the changes you have made, or select Cancel to return to the style. If you quit from EndNote while a Style window is open, the same dialog appears.
EndNote automatically saves new styles to your personal Styles folder. You may also specify a different folder if necessary. For instructions see Folder Locations Preferences.
EndNote styles use the file name extension of ". ENS" (for EndNote Style), as in " Nature.ens."
