You might want to delete saved document conversions if your Filr system is running out of disk space or if existing document conversions become out of date or corrupted for any reason. After the document conversions have been deleted, they are re-created the next time a document is viewed in HTML.
Document conversions are automatically deleted when the Filr appliance is restarted at a time when the /cachefilestore/converted_html_files directory exceeds 10 GB, as described in Section 16.1, Understanding Document HTML Conversions.
To manually delete all saved document conversions:
Purge the /cachefilestore directory.
Re-create the /cachefilestore directory at the same location.
