Step 1:

First, Find your zip file & double click on it. This will execute a program to unzip the file. If you are given a message saying that you don't have software to do this, go to 7 Zip and download 7 Zip for free. Now, when you receive a Zipped up file, you just need to double click on the zip file, and 7-zip will should automatically execute and open the file. You are not done yet, you can't use the file until you extract the data from the zip file.

Step 2:

Using your mouse, select your folder(s) and then click on extract. This will take all the data inside that zip file & make it so you can view & use it.

It is going to ask where you want these files saved. Pick the spot on your hard drive that you want to save it.

Then you are done!
