Compressing or "Zipping" a File/Folder

1. Open Finder.

2. Find the file/folder you want to compress.

3. Various ways to get the file compressed:

• Hold down control and click on the file or folder, and click Compress from the shortcut menu.
• Click the file or folder and click on the gear in the finder window and select Compress.
• Two finger click the file from the track pad then click on Compress.
  
  

4. This should produce a .zip file with the same name as the file/folder in the same folder as the file. If you compress multiple items at once, the file will be called Archive.zip.
