Dropbox is a free utility software that allows users to store, manage, and share files through the cloud. It seamlessly synchronizes contents across several devices allowing you to easily access your files, whenever and wherever. Users can also upload files across a wide array of file types, and even host group projects and team collaboration. Note, however, that the free service caps at 2GB of storage. Users exceeding this amount must either delete some files or upgrade to an advanced service.
