Once you click on the "Download" button on the final page, a box will pop up with two options: Open or Save. Please click on the "Save" button, and save the file to your computer first before you open it.

Many of the files for sale will be in .ZIP format. A ZIP file uses the .zip file extension and is used to compress files into one folder.

For Windows users, if you have purchased a ZIP file, the first step is to save the zip file to your computer and then navigate to your folder. To unzip the file, you will have to right-click on the folder and select "extract."

For Mac users, if you have purchased a ZIP file, the first step is to save the zip file to your computer and then navigate to your folder. To unzip the file, you will have to double-click the file you wish to unzip. Your files will be unzipped into the same folder as the original ZIP file.

For Linux users, open a shell prompt and enter the following: unzip myfile.zip.
