Can we organize with folders?

Yes - you can move QR codes into folders to keep them organises (and you can also use tags)

A QR code can only be in one folder at a time. You can filter your dashboard by a specific folder, all folders, or "unfiled" which shows all QR codes that are not in a folder.

To add QR codes to folders, click the "Select" button on the top right of the QR codes in your dashboard

Select the QR codes you want to move, Then select the folder or create a new one.

You can then filter the dashboard by the folder from the drop down menu on the left

If you want to delete a folder, you can do it from Settings -> Folders. When you delete a folder, you can decide whether you want to QR codes in it to be moved to "Unfiled" or if they should be deleted.
