Dropbox is a cloud-based file-hosting service established in 2007 that offers solutions for storing, sharing, and collaborating on files and documents. It allows users to save files to a cloud server and synchronize them across multiple devices, including smartphones, tablets, and computers. This synchronization ensures that the latest version of a file is always available, regardless of the device being used. Dropbox provides various features such as file versioning, which keeps older versions of files for recovery; shared folders, which allow multiple users to collaborate in real-time; and Dropbox Paper, a collaborative workspace for teams. The service is available in free and paid tiers, with the latter offering more storage space and advanced features like enhanced security and administrative tools for businesses. Its user-friendly interface and robust functionality make Dropbox popular for individuals, professionals, and organizations looking to streamline their file storage and collaboration processes.
