Description
We have noticed a server running out of storage because /var/cache/tomcat9/Catalina/localhost/ROOT/xwiki-temp was using up 15GB of space.
On closer inspection, the folder was full of many such folders which seem to be produced by the Office Importer Application:

The contents of such a folder are:

It looks like these temp files/folders never get cleaned. Upon tomcat restart, the files seem to be deleted automatically, but that's not very useful.
We need to make sure to properly delete each such temp folder after a conversion is complete, regardless of its outcome and where it was performed from.
