Open RUF File
The RUF file is a firmware image file, which is used by Samsung Blu-ray and DVD players.
The RUF file contains operating system-level functions that make the player work and is used to display firmware updates using a USB storage device.
Updates contained in an RUF file, or in firmware, can be performed by connecting the USB drive containing the file to the player.
It is important to know that the USB flash drive must be empty except for the RUF file for the firmware to update properly.
