Generic RAR archive of 2.11 MB whose name gives no device, brand or board information. Judging only by the title it probably holds pictures, which in repair collections are often board photos, component placement shots or annotated measurement points. Open it with WinRAR or 7-Zip and inspect the contents before using anything for diagnosis. Since nothing identifies the hardware, compare any photos carefully against the actual board number and revision printed on the PCB before relying on them.
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 @mobileshematic. Enginerys does not host this file.
