ownCloud

ownCloud is an all-in-one program for saving, synchronizing, viewing, editing, and sharing files, calendars, address books, and other content. It is for people who want one program to cover those tasks. Users can save files, keep them synchronized, open them for viewing or editing, and share them with others. They can also work with calendars and address books through the same solution. This combined approach keeps file, schedule, and contact-related work within one program. ownCloud may be less suitable for someone who needs only a single-purpose file, calendar, or address book tool, because its scope combines all of these areas. It is an all-in-one option rather than a narrowly focused program. That breadth can be unnecessary for users with one simple task.
