I needed to create two libraries to reflect different work. After i created the second library, I renamed the first one from the .enl suffix. When I then opened this library, it first requested that I link it to the .data file, which I then also renamed. After doing this, I opened the library and discovered all the existing references had disappeared. Where would they have gone?
The original name will have a .DATA folder with that name. If you rename the .DATA folder to have the same name as your renamed .enl file, it will “magically” recover the original library contents - well it really isn’t magic - the most important information is always in the .DATA folder. The .enl file is more of a “pointer”.
