Stage 3: When you want to check the size of a folder, click the Google Drive icon in the system tray (PC) or menu bar (Mac) and then click the More (three dots) icon. Note: If you do not want to upload your documents or image to Google Drive, you must specify your preferences in the second step of the Welcome to Backup and Sync setup. Click Start to run Google Drive on your PC or Mac without downloading any data.

Step 2: During the third step of the Welcome to Backup and Sync setup, make sure to uncheck the box next to ‘Sync my Drive to this computer’. Stage 1: Download and install Google Drive Backup & Sync. However, instead of syncing your data locally and then checking folder sizes using File Explorer or Finder, the steps below should show you a method with zero downloads as well as the initial Backup and Sync download. If you don’t want RaiDrive to access your Google Account data, or if you’re using a Mac (in which case RaiDrive isn’t supported), you can instead use the Google Drive Backup & Sync client to control folder sizes.
