Minimum installation of phpdocx
The whole of the files of the phpdocx Advanced license requires 48MB of hard disk space. But maybe you wish to minimize the necessary disk space to run phpdocx. In that case, you can delete the plugins and examples folders, and the files check.php, check-conversionplugin.php.php, Readme.txt and LICENSE files from the root folder.
This is how the folder tree looks after removing all the non essential content in an Advanced license.
