Aurora Files documentation

Office document viewer

Default viewer

To view files of office document formats such as .DOC or .XLSX, Aurora Files uses an online viewer from Microsoft.

If you experience issues with viewing those files, you can try switching to a viewer from Google.

In data/settings/modules/OfficeDocumentViewer.config.json file, set ViewerUrl value as follows:

"ViewerUrl": [

Please note that in either case, your Aurora Files installation needs to be accessible over the web, so that online viewer can have access to it. Viewer from Microsoft is also known to fail at displaying the document if your Aurora Files installation is accessed via IP address rather than domain name.

OnlyOffice Docs viewer

Starting from v8.8, Aurora Files offers OnlyOffice Docs integration - and if you have office document editor configured, OnlyOffice Docs will automatically be used for viewing documents as well.

Additionally to office document formats (.DOC, .DOCX, .ODT, .XLSX and so on), the viewer also supports:
• PDF and XPS documents;
• RTF, TXT and CSV files;
• HTM, HTML and MHT web pages;
• FB2, EPUB and DJVU e-books.

The complete list of formats supported by the viewer is a combination of ExtensionsToView, ExtensionsToEdit and ExtensionsToConvert lists found in data/settings/modules/OfficeDocumentEditor.config.json file.
