Archive named after the H110M-E-M2 motherboard, an Intel H110 chipset desktop board, though the name does not state the brand or what the 13.4 MB RAR contains.

If it holds a BIOS image, compare its size with the board's SPI chip and back up the existing contents before writing with a programmer, and confirm the model printed on the PCB is the same.
