A. 1. Check the 'Deleted files' section: Open the Dropbox app, go to the 'Files' tab, and look for the 'Deleted files' option. You can restore files from here if they were recently deleted. 2. Use the web interface: Log into your Dropbox account via a web browser and check the 'Deleted files' section there for recovery options. 3. Enable file versioning: Ensure that file versioning is enabled in your settings, which allows you to recover previous versions of files.

B. 4. Regularly back up important files: Use another cloud service or an external hard drive to back up critical files to prevent loss.
