Dropbox has added a new feature that allows users to sync other folders, including Desktop, Downloads, and Documents, in addition to their Dropbox folder. This feature is currently available as a beta test for some users, but most users have access to it. To set up this feature, users need to go to their Dropbox settings, select the folders they want to back up, and save them. The backed-up files will be synced across devices and can be edited on other devices, with changes syncing over. However, there are some limitations to this feature, such as not being able to use it for two-way synchronization between computers and not being able to share backed-up folders via email invitations. This new feature also opens up opportunities for automation using services like Zapier, allowing users to trigger custom automations by moving files into a folder on their desktop.
