Small RAR archive of about 2.1 MB for the Motorola Moto G7 Play, model XT1952. The name does not state what is inside, but such packs commonly carry schematic pages, layout images or reference measurements for the phone mainboard. These help a technician find components, compare diode-mode values and track down shorts on power lines. Extract it with a standard archiver and verify the XT1952 sub-model printed on the device, since variants with different suffixes can use altered parts.
