Detecting version used
Navigate to login page of your Aurora Files installation and once the page is opened, view its source code (e.g. Ctrl-U in Mozilla Firefox). At the bottom of the code, you should see something like:
<!-- 9.6.1.build30-build-a3 -->
This means that Aurora Files version 9.6.1 (build 30) is installed.
Alternately, if you have filesystem-level access to the installation, check VERSION file in root directory of Aurora Files installation, it contains the version number.
Another way to check that in Aurora Files is to log into /adminpanel/
as superadmin and open 'About' tab of admin interface, you should see something like:
About
Name: Afterlogic WebMail Pro PHP
Version: 9.6.1.build30-build-a3
