Kontainer is a great tool for online file storage and sharing -- for videos, images and any other type of file. Many people still use FTP servers as their main tool for storing and sharing documents but with Kontainer, you can instantly, easily, and from anywhere, upload and send any type of file, including documents, photos, and videos to clients, collaborators or suppliers. When you upload a document, a preview is automatically generated and lets you and your other users have a quick overview of the file before downloading or modifying it.
