Almost 99% of the files sold through our site are downloaded as zip files. Zip files are archive files that basically store several files together for easy downloading/uploading through the web.
Most modern computers come with a program that automatically can open up zip files and reveal the contents within. However, if you're on an older computer, you'll need to download a program. OR just try this - right click on the downloaded zip file and click on "Extract Here". It will get extracted as a normal folder there itself.
Here's the program we recommend - WinRAR. Download it here: http://www.rarlab.com/download.htm (make sure to choose the correct version).
