Hello, im new here, when i try to add a local script i just have to put the .jar in the script folder, no big deal. but when i download some other scripts sometimes they come in a .zip and if i extract them they will be .class files, how can i convert .class to .jar >?

a jar is simply a collection of class files. You can just rename the .zip to .jar as it was probably a .jar originally and winrar is interfering.

You just place the .class files inside the script folder just like the .jar file.
