.ENQ File Extension

File created by EndNote, a program used for managing citation information; saves options for performing a citation search; may include author name matches, journal matches, date ranges, or other filtering parameters; helps save complicated search criteria; can be transferred between EndNote users for sharing search options.

You can create an ENQ file by entering search criteria (click the Online Search... button in the application library bar to enable search), clicking the Options button, and choosing "Save Search." You can load search options by double clicking an ENQ file or by choosing "Load Search" instead of "Save Search."
