<p>All uploaded files from the Media section will appear on the ONLYOFFICE Docs -> Files page. The editor opens in the same tab by clicking on the file name. Users with administrator rights are able to co-edit documents. All the changes are saved in the same file.</p>
<p><strong>Creating a post</strong></p>
