Numbered RAR archive, 101, of 3.74 MB, carrying no brand, model or board information in its name. What it contains, schematics, layout, firmware or documentation, can only be learned after extraction. In a repair library such packs are typically used for following power and signal paths, locating parts and test points, or restoring software. Unpack it with a standard archive tool, identify the device from the files themselves and make sure board number and revision agree with the PCB before relying on it.
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 @tamirat_moobile. Enginerys does not host this file.
