7z archive of about 1.94 MB holding firmware material for the Xiaomi RedMi Note 2, code name hermes. A package this small usually carries a scatter or partition layout, a loader, or boot and recovery images for service work rather than a full ROM. It is used when repairing a bricked unit or fixing partition damage with a flashing tool. Open it with 7-Zip and check that the contents match the hermes hardware. As with any phone flash, keep a backup of the original partitions before you write.
