I downloaded Raspbian Stretch with Desktop to install on my PI. Once it completed, I tried to extract the file, but the window complained that there is not enough space that I need some 470 GB MORE. What is going on? I simply went to https://www.raspberrypi.org/downloads/raspbian/. Then started to download ZIP file. Any idea.
The Raspbian stretch image is 1.9Gb and when unpacked becomes 4.7GB. Are you using a big enough SD card. 8GB minimum
Even though this question was requested by two people to be closed, I think it will help someone who is working with PI extensively like me.
When you have a problem like this, simply download 7-zip for your system and extract the Zip file with this program.
