Notes about the UPG file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The UPG file type is primarily associated with 'Firmware Upgrade File'. There should be an associated .EXE file that uses the .UPG file to install new instructions into the firmware. Many different hardware makers use this file type for upgrades. They all have different formats so there is no single way to handle this file type.
