To start using Dropbox as a beginner, sign up here for a free dropbox basic account with 2 GB of storage. Log into your dropbox account using your credentials by dropbox.com, desktop app, or mobile app. Click on the "Add" option to create new folders and add files to them. To share or delete any folder or access other settings of a folder, click on the three-dots icon next to that file/folder's name and choose the relevant option. To recover deleted dropbox files or data, go to the deleted files section and restore the data.
