When sending a complete folder of documents, how do I compress it for email sending?
Select the folder you wish to compress. Select File -> Compress from the Finder Menu Bar.
A new file with the extension .zip will be saved in the same location as the original folder.
Use the "zipped" folder as an attachment in your email. When the email is received, the recipient will need to save the zipped attachment to their computer, then double click it to expand the file to display the original file or folder.
