There are 2 file types use the .LYR file extension:
1. ArcView Layer File
Contains information available in ArcView's layer properties dialog box; may include symbols, display settings, joined table details, definition queries, labeling properties, and annotation display properties.
LYR files are similar to Legend (.AVL) files, but may contain much more information and are saved in a binary format rather than as a text file.
