There are many files involved with projects: requirement docs, content docs, status reports, website images etc. It is inefficient to communicate project files via e-mail; we utilize Dropbox. Think of Dropbox as a place to store files on the internet (cloud-based storage) that we can both access and update.
What is Dropbox?
Dropbox offers cloud storage. Files are stored at www.dropbox.com on secure online servers.
Dropbox files sync with your devices. You can view/edit files on your computer/tablet/phone and they are automatically synced with dropbox.com.
Dropbox files can be shared amongst multiple Dropbox users. Each user can view/edit shared files.
