Generic archive named only edit, 3.01 MB in RAR format, with no model, brand or board number stated. The name suggests a modified file, perhaps an edited firmware image, but the contents cannot be identified without opening it. Extract it and examine any image with a hex editor or BIOS tool to learn which board it belongs to. Never write an unidentified image to a flash chip; back up the original first and make sure the size matches the target chip before programming.
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 @iranianRefix. Enginerys does not host this file.
