As an administrator, you can provide preview tools to your users so that they can quickly view a portion of a document to determine if it is the one they need to work with. 

 1. After selecting a file in the User Portal, a Preview button is available.

 2. After clicking the Preview button,
a separate window opens showing an image of the file.

This preview image cannot be edited.

There are three ways an administrator can provide preview tools in FileCloud:

  • Enable Quick JS Preview (FileCloud version 19.1 and later)
  • DocConverter with LibreOffice (FileCloud version 18.2 and earlier)
  • WOPI - Web Application Open Platform Interface Protocol (Supports online web editing features)


 What is DocConverter?

FileCloud uses a Java-based service called FileCloud Document Converter to:

  • Enable thumbs for all Microsoft Office documents (DOC, DOCX, PPT, PPTX, XSL, XSLX)
  • Enable thumbs for Adobe documents (AI, PDF, PSD)
  • Enable thumbs for TIFF images
  • Interface with LibreOffice for document preview generation

For this FileCloud uses a java program based on Apache's PDFBox.  Document converter also will use LibreOffice libraries to convert documents to PDF.

FileCloud Server version 19.1 and later already includes the Doc Converter jar file and it is installed automatically. 

  • You do not need to download it as you did in earlier versions.

(warning)  In FileCloud version 19.1 and later, Document Converter for Windows is automatically installed and ready to enable in the Admin Portal.  

1.   If you are running on Linux, start Doc Converter on your server.

FileCloud Document Converter for CentOS


2.   Enable thumbnail images on the Admin Portal.

Enable Document Thumbs



 What Other Online Web Editing Features Are Available?

Administrators can configure online editing to allow FileCloud users to select any supported document and edit the document from within the User Portal.

  • FileCloud uses the WOPI (Web Application Open Platform Interface) protocol to support online web editing

To use WOPI, you must install or have already available one of the following to provide the web editing capability:

  • Microsoft Office Online
  • Collabora Code

You can choose which tool to use not only by the versionof FileCloud you are using, but also by the functionality.
