We recommend you make backup copies of your EndNote library in case you computer crashes or you need to transfer files from the C account (the hard drive) to your G account (the university network account). You can do this as described below or by syncing your desktop and online libraries.
When you create a new EndNote library, the program will create one EndNote library text file and one EndNote library data file folder. The text file has the file extension .enl and includes all your references, and the data file folder has the name extension .Data and includes any added PDF files and other types of files. The data file folder is created automatically and has the same name as your EndNote library, either the default name My EndNote Library or a name you have chosen yourself. They are also, by default, placed under Documents on your computer.
If you rename your EndNote library you must also rename the corresponding data file folder. If you don't do that EndNote will think your library is broken since it cannot associate your references with other necessary files. This is also the case if you want to make a backup copy of your library. You have to make backup copies of both the EndNote library file and the corresponding data file folder. So a better way to manage this is to use the Compressed Library (.enlx) function.
When you save and make backup copies of your library using the compressed library function, EndNote saves the library file and the data file folder as one single file with the extension .enlx (titled Archived EndNote Library on your computer).
