Hi Stephan, Thanks for the prompt reply.
Perhaps I should have been more specific. Let's say the Filename is /tmp/per%cent. When The Directory Resource is directed to /tmp as it's base it will display the problematic file as <a href="https://localhost/resturl/per%25cent">per%25cent</a> This I completely understand. Following the link however results in Error 404, whereas the other files with no percent in their name work correctly. I appreciate that the filename needs to be percent encoded in order to participate in the URL, however I suspect there is an issue in the unencoding, or at least the resolution of the filename used to access the FileSystem. Thanks Again Andrew.
