When you display a list of filters in EndNote, the list is comprised of the installed filters found in the Program Files\EndNote\FiltersApplications/EndNote /Filters folder as well as new or modified filters found in your personal Filters folder. For an explanation of where your files are stored, see Folder Locations Preferences.
There are two ways to copy filters. Since each filter is a separate file on your hard drive, you can copy them as you would copy any file on your hard drive using the Macintosh FinderWindows Explorer .
To make a copy of a filter from within EndNote:
From the Edit menu, select Import Filters and select Open Filter Manager.
Select the filter you want to copy and click Edit.
Without making any changes to the filter, select Save from the File menu.
Give this copy of the filter a new name, and then save it.
The file is saved in your personal Filters folder. The new filter will remain open. The original filter will be left untouched.
