Let me clear what's the question is, i seen some files where one type of file is located with it's dll and just a cmd needed to extract files in it instead of using full software.

Example: seen some .arc file located with it's dll and just a installer kinda stuff (*.exe) extract files in it instead of using freearc software or any other software which support that file type.

So I have one file " .paq8o " , when I googled , it shows it can be extract with peazip but is there any other way I can extract it without using peazip?

PS: sorry for my English ..lol
I'm new here so no idea about all these stuff , that's y asking
