A broad and open question, but in summary think about the higher versatility you get by having your files in the cloud rather than on local disk(s), better versioning/forking, easier sharing with others and also faster deployments. Needless to say that such a tool can make the whole process much easier for teams. The bigger your project, the more you get out of cloud development. Read more in About and FAQ pages.
If it is somewhere on your local system, you've got several options: either you can upload the whole project as a ZIP file and upload it on the Devello treeview, or you can create your project by importing this ZIP file, in addition you can drag and drop files into the solution explorer. Also you can enter your repo name when creating the project, to have all repo files imported immediately if your project is hosted on Github. Furtheremore, there is an aption for importing FTP contents.
Of course not, anyone can use Devello Studio to make and release a project but you'll get more by registering. Private projects, inviting users to edit/add files and having your own custom set of projects are just a few extra features available to you after login.
