Dropbox is a file hosting service in the cloud that can be accessed from any device at any time.
Dropbox is downloaded and installed on computers, smartphones and Kindle Fire so you can have your photos, documents, videos, music and any file always available. This service allows you to store and sync files online and between computers as well as share files and folders with other users, public or private.
In order to save the files you need to create a Dropbox account. This application offers three types of accounts with various options: one pro, one for business and one free, with 2 to 18 gigabits file storage free.
Once you've created your username and downloaded the app you can place inside the Dropbox folder on your computer, the files you want to share. Depending on the number and weight of the files, you'll have to wait more or less time for them to be synchronized and made available to access them from another location or device.
In short, Dropbox is a software that links all computers that use by a single folder, which is an easy way to back up and synchronize files and folders.
