Cloud Drive is a free client software for Adobe Acrobat Online Storage Service, which offers 5GB free online storage for each account.
Although Adobe, like most other cloud storage solutions, such as Google Docs and Microsoft Skydrive, offers file uploading/downloading, none of them allows folder uploading! Furthermore, uploading bunch of files can take hours to finish, during which time the webpage cannot be closed – quite the inconvenience!
Cloud Drive enables you not only to upload/download groups of files and folders, but it does so silently and in the background, without cluttering up your taskbar with one more browser, or one more open window getting in the way. It works with a simple drag and drop.
