We often provide zip files for our bundles and products. You can unzip a file very easily on Windows without the need for additional software.
Once you have downloaded the zip it should appear in your downloads section of the PC.
Next, right click on the file and click ‘extract all’
You will be asked to name your folder and choose where you would like to extract it to. Choose the relevant option and click ‘extract.’
The file is now unzipped/uncompressed, and you can can now access the files within.
