Thank you for replying. I read this that OwnCloud is shifting to LibreOffice or Collabora. I want to know where i can find this configuration files or code to look at it. Also, is there a similar way to Collaborate simultaneous with the documents but using Office. For example if i have Office Document (docx) and i open it and start editing, and if some other user open it and start editing, can we see the changes without saving the document ?
