BIOS archive for an X409FB laptop mainboard at revision 2.0, marked with FL8700FJ, a code that looks like an ASUS board identifier, packed as a 5.11 MB RAR. The X409FB is an ASUS VivoBook model name, though no brand appears in the file name. The image is meant to be written to the SPI flash chip with a programmer to revive a board that no longer boots. Check the revision on the PCB, save the original chip contents, and compare the image size with the flash capacity.
