What is an LRLIB file?
An LRLIB file is an archive created by Adobe Lightroom CC, a digital photo management and editing application. It contains information about a library created in Lightroom CC, which includes each original image imported in the program and the .MCAT catalog file. LRLIB files are the same as the more commonly used .LRLIBRARY files.
LRLIB files are typically located in the "Pictures" folder of your home directory. When you import pictures into Lightroom CC, information about each picture is added to the LRLIB file.
NOTE: Lightroom was formerly known as Photoshop Lightroom.
