I downloaded about 5 programs and none of them are like the file options in windows 7. In particular you can't give arguments to commands that you're going to open the program with.
I tried writing registry files myself, and it's an incredible nightmare. Most of the time I try it now nothing happens, other times everything is changed after I restart my computer. I just want file options, I can't understand why Windows 7 doesn't have that basic tool!!
