Google Drive now allows you to add a single file to multiple folders and Shared Drives with Shortcuts. Shortcuts are pointers to files that are stored in another folder or Shared Drive, which makes it easy to reference contents without creating copies of the file. To create a Shortcut:

1. From your Google Drive, locate the file for which you would like to create a shortcut.
2. Right-click on the file and select Add shortcut to Drive.
3. Select the shortcut location and click the Add Shortcut button.

Note: Shortcuts are visible to anyone who has access to the folder or Shared Drive containing the shortcut. Even if someone can see the shortcut, however, they can only open it if they have the appropriate access to the original file or folder.
