Important General safety notes
EndNote libraries are made up of two parts: the .enl file and the .Data folder. These two parts must be kept together; both are needed for the library to work correctly.
Keep EndNote libraries on your computer's local hard drive. Storing and editing libraries on a network drive can lead to corruption and performance issues.
EndNote libraries should never be stored in cloud-syncing folders such as Dropbox, OneDrive, Box, SugarSync, etc. Syncing folders corrupt EndNote libraries over time.
Uninstall your previous version of EndNote before installing a new version.
Synchronize references in EndNote libraries between desktop and laptop computers, the online library, and an iPhone or iPad using EndNote Sync.
Share complete EndNote libraries with other EndNote desktop users through EndNote Sync and Library Sharing.
macOS Sierra, High Sierra, Mojave, Catalina, Big Sur and Monterey users
Apple's macOS versions 10.12 (Sierra), 10.13 (High Sierra), 10.14 (Mojave), 10.15 (Catalina), 11.0 (Big Sur) and 12.0 (Monterey) contain features to save the contents of the Documents folder in iCloud and to "optimize" storage by storing less-used files only in iCloud online. EndNote libraries stored in iCloud, even when stored on both the hard drive and online, are subject to corruption over time. If you choose to store your documents in iCloud, we suggest creating a separate folder in your Home folder and saving your EndNote libraries there. Do not store EndNote libraries in iCloud or any other cloud-syncing folder, and do not store EndNote libraries in the Documents folder if you have selected the option to synchronize documents in iCloud.
