Extracting From a .rar Archive

This is mostly irrelevant on Cults which no longer accepts archives (which is a pain on my end) but a few of my old files from before this still use them. However archives are and have been very commonly used across all computing for over 20 years since the days of floppy discs, including massively in 3D printing for sharing and transporting of .stl and associated files. If you want to get into 3D printing, you will have to become familiar with archives. They are an accepted format for uploading by almost all services and have the benefit of compressing the size of the file within. To extract your .stl file from a single archive simply right-click the archive and click 'extract here' or other similar option. Windows by default includes the Winzip program to do this, but you can also use the superior Winrar (https://www.win-rar.com/download.html) or 7zip (https://www.7-zip.org/download.html). If you are using a Mac you will need to download The Unarchiver (https://theunarchiver.com/) from the app store in order to effectively work with archives, or Keka which is a similar alternative (https://www.keka.io/en/)
