<p>Certain file types will not open directly from HyperDrive.<br /><br /><strong><span style="font-size: 12pt;">Explanation<br /></span></strong><br />HyperDrive uses a WebDAV connection, which is a Microsoft-developed architecture.<br /><br />Because of this, only specific Microsoft files will open directly from HyperDrive. These include word, excel, powerpoint, and other MS Office files.<br /><br /><strong>Files that should open directly from HyperDrive if you have MS Office:<br /></strong><br />MS Word (.doc)<br />MS Excel (.xls)<br />MS PowerPoint (.ppt)<br />MS Infopath (.xml)<br />MS Publisher (.pub)<br />HTML files (.htm .html)*<br />Image Files*<br /><br /><strong>MS Access and other database files<br /></strong><br />HyperDrive is a direct connection over the web. Databases like MS Access and Quickbooks require open connections to them. This does not work over the web using WebDAV. Database files should be dragged and saved to your desktop first, then opened locally.<br /><br /><strong>Note regarding PDF files<br /></strong><br />While Adobe Acrobat PDF files are non-Microsoft file formats, these files should open normally through HyperDrive.  If they do not, please refer to our article on opening PDF files.</p>
