Large 34.1 MB ZIP archive named SKR.03, with no brand, model or document type stated, so the contents are unclear from the name alone. SKR is a token often seen in universal TV board firmware sets, but that cannot be confirmed here. Open it with any standard archiver and inspect the files before use. If it holds firmware images, match them against the board marking and panel resolution, confirm image size equals flash capacity, and always back up the chip you intend to reprogram.
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 @hashmielecom. Enginerys does not host this file.
