Hello,
It is possible, but you need to have file in attachments section.
You can see an exemple in my screenshoot.
 

When I open the email menu I see all the fields like the picture you showed , only the file attachement section does not appear for me , is there any configuration parameter that I need to add or any php parameter to configure to make this section appear in our menu of email sending.

You need to have files attached to the item.
 

Hello Babynus 
Thank you for your reply.
we have files already attached t the activity.
please see the first screen capture.
also see what take a look  in the email menu that we have  , there are noa attached files although they exist in the activity.
Thanks for your help and assistance  

  
this what we have in paaprmeters.php file :

<?php
// =======================================================================================
// Automatically generated parameter file
// on 2017-05-04 17:39:46
// =======================================================================================
$paramDbType='mysql';
$paramDbHost='gsolutionsconsulting.com';
$paramDbPort='3306';
$paramDbUser='rootgsc';
$paramDbPassword='mysql';
$paramDbName='projeqtorgsc';
$paramDbPrefix='';
$paramDbCollation='utf8_general_ci';
$SslKey='';
$SslCert='';
$SslCa='';
$logFile='../files/logs/projeqtor_${date}.log';
$enforceUTF8='1';
//======= END

is there any string to put here or any other config file regading emil file attachement and/or directory for file attahcement ?

hi have seen a such similar case any where ?

This issue has been solved by putting bibliothèque php instead of php mailer in the consfiguration of the email in Projeqtoria.
We have hosting our Projeqtoria n godadday and this is the only configuration that work in which we see the files attached’

our hoster is gdaddy , the only parameters that would allow fie attanchements is using the email method php library this will work on all similar hosters and softaculous installations
