Compressed RAR package for the ASUS E410MA notebook, with R7.1 in the name, most likely the board revision. At 13.9 MB it could hold a schematic, a boardview or a BIOS image, and the name does not say which, so open it and check the contents first. Technicians use such packs to trace power rails, find components and test points, or reflash the SPI chip. Before relying on anything inside, compare the revision printed on the PCB with the files, because ASUS revisions can differ in layout and part placement.
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 @biositechyangiyer. Enginerys does not host this file.
