// Here after
// $host is the path to the repository directory 
// $root is the repository directory (i.e. $host + "data/")
// $path is the root + the year and month sub-directories
// When using the default installation directory, $host remains "" (empty string) and $root is thus simply "data/".

// If you want to store the messages in an other directory:
// the fullpath of your storage location must be declared in the bin/qtg_init.php file: in the variable $qtg_host (with final /) 
// Example: To store data in //storage/qtg/data/ you must declare $qtg_host = "//storage/qtg/" in the bin/qtg_init.php file
