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.|

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)
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.
1. Start the Doc Converter service and configure it with FileCloud.
Windows: LibreOffice Windows Instructions
2. Enable thumbnail images on the Admin Portal.
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 version of FileCloud you are using, but also by the functionality.
|Tool||File Types Previewed||Preview Keys||Interactions with Other Tools|
|Quick JS Preview||None|
|DocConverter with LibreOffice||SHIFT + Preview|
|WOPI||None||WOPI will override any Quick JS or DocConverter functionality|
