Is there a way to open .rpf without the game itself?

[LMB 2]

So I backed-up the .rpf for Stories from Liberty City, but not the EFLC.exe.

 

Is there a way to open it without the .exe file?

 

Thank you.

You need to have exe (in your case from GTA IV or EFLC) to open game archives because OpenIV reads encryption keys from EXE file. You no need the whole game.
