Hello world! I'm talking about zipping the files in a C sharp project . I have a myCSharp directory and I have a number of projects that I've created. Here's one called computer and we have sln, and then a folder called computer . this is the... computer is inside another folder called computer. we want to zip at the top level so that it will have the both the file called sln, and the folder called computer. I'm going to right-click win-zip, add to computer.zip and it shows me that it's compressed it quite a bit. And that's OK. Here it is way out here, okay if we open up that zip file, you'll see that inside that whole thing it has the computer directory and the sln, and everything we need. and that's what we want to do when we zip those projects. And that's it!
