Description

While running Tika 1.16 in detect mode over some legacy files from our repository system, I came across one file with a .wpd extension for which Tika reported the following mimetype:

application/x-quattro-pro; version=7-8

Opening the file in LibreOffice reveals this is actually a WordPerfect document (not sure about which version; the .WPD extension suggests WP 6 or later). I had a look at the Quattro Pro entry in tika-mimetypes.xml:

      <mime-type type="application/x-quattro-pro">
        <_comment>
          Quattro Pro - Corel Spreadsheet (part of WordPerfect Office suite)
        </_comment>
        <!-- qp2 and wb3 are currently detected by POIFSContainerDetector
            TODO: add detection for wb2 and wb1 -->
        <glob pattern="*.qpw"/>
        <glob pattern="*.wb1"/>
        <glob pattern="*.wb2"/>
        <glob pattern="*.wb3"/>
      </mime-type>

This suggests that the problem originates from POIFSContainerDetector.

For legal reasons I cannot share the original file. However I was able to create a derived file by truncating the original file after 18 kB, and this derived file shows the same behaviour. The file is available at this link:
