The zip file format is a compression format used to compress one or more files. Using a Zip program such as Winzip or Pkzip will allow you to decompress the zip file and give you access to the files within it. |
To decompress a file, first you need to download one of the above zip programs. Then install that program to your computer.
Then, after the installation, you double click on the file you would like to open.
Click on the extract button and choose the destination folder to which you would like to extract the files. (An empty directory is preferable.)
Most zip files downloaded from FreeCADApps.com come with instructions written into a readme file or a text file. These instructions will guide you the rest of the way.
