Zapier is a workflow automation software that allows users to create automated workflows called Zaps, which send information from one app to another without coding knowledge required. The goal is to save files from emails directly to Google Drive automatically, eliminating the need to remember to upload them manually or scroll through emails for days/weeks old attachments. To achieve this, a Zap can be set up using Zapier's "Email by Zapier" trigger and "Google Drive" action, where the user creates an email address that is used as a trigger, sends an email with an attached file to it, and then sets up the Google Drive action to upload the file automatically. This eliminates the need for manual uploading, saving time and effort.
