Large 108 MB RAR collection of boardview files with a generic name, giving no brand, model or board numbers. It is probably a bundle of layouts for many laptop motherboards in formats such as BRD, CAD, FZ or BDV. Extract it and search by the board number printed on your PCB to find the matching file. Boardviews open in viewers like OpenBoardView or FlexBV and help locate components and test points, but always check the revision since several versions of a board may exist.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @ITHINKHS. Enginerys does not host this file.
