Google Drive Tip
Add your document to multiple folders using "shift-z"
1. Go to your Google Drive and highlight the file you want to add to a different folder
2. Hold down the shift key and z
3. Select the folder
3. Select the folder
3. Done!
Beware: If you delete the document, it will disappear from all folders. This is because "shift-z" doesn't copy the actual file to the folders, but adds a point to the real file (wherever that file is).
Want to remove the file from a particular folder? Right-click on the document and select "view details" then select the "details" tab. You'll see the parent folders listed under location. Remove a folder by clicking on the "x" next to it.
