Workaround, Google shares longterm plan

Thanks to comments from our readers and input from Google’s Remy Burger, this post has been updated to reword and clarify a few points, specifically regarding file ownership and consequences for companies and G Suite users. Remy also shared with us a workaround and the Drive team’s longterm plan.

First, you can still move shared files and folders to your Drive, even on the web (no need for the Android app), but the option is hidden behind a keyboard shortcut. Go to your Shared with me section, highlight the shared files or folders you want to move, and type Shift+Z on your keyboard. You’ll see the old move menu and can choose where to put those folders. On your PC, they’ll sync and behave like they used to, no shortcut mess. More info can be found here, and you can always type ? in Drive to bring up the list of keyboard shortcuts if you forget this one.

Shift+Z brings up the old Move menu, letting you add shared folders to your Drive.

Finally, Remy revealed that the Drive team will “keep this behavior [Shift+Z] around for folders until we have a solid solution to sync shared folders.” I think that helps appease our collective fears about the change. As I mentioned earlier in the post, a lot of issues would be solved once Google’s Backup and Sync started recognizing shortcuts as folders and synced them as such. You’ll still need to explain to others how the change affects where files “are” and how sharing privileges can be revoked if they move a file out inadvertently, but the bulk of our complaints about this new system will be gone. Hopefully, Google figures out a solution for syncing shared folders quickly.
