Microsoft added Office Online (known at the time as Office Web Apps) capability to OneDrive in its "Wave 4" update, allowing users to upload, create, edit and share Word, Excel, PowerPoint and OneNote documents directly within a web browser.
OneDrive allows the viewing of documents in Portable Document Format (PDF),[REF] and in the Open Document Format (ODF), an XML-based file format supported by a number of word processing applications, including Microsoft Office, LibreOffice, OpenOffice.org and Corel's WordPerfect [REF].
