What file should i change to update a module version number?

[Billy]

So i have a paypal module that i did some minor work on years ago. How can a change the version so it's not overwritten by TB? The version of that module is "PayPal v3.11.1 - by PrestaShop"

[colorful-ant]

change the module/paypal/paypal.php

for example find this and change it

$this->version = '3.11.1';

Perfect and i changed the v to 9.11.1 hope that works. 

I attached the module for later reference. As i need to grab the paypal api password from the main website database. I can't seem to find that password. So I will need a little coaching to trick paypal into thinking nothing has changed. (I hope anyway after cloning that is.)

Thank you for such a fast response!

I did not know that it is possible to change the version no. by myself, not to updating it by the shop.  This is cool and easy.  I was in the situation that i needed this, so maybe i can give an older (better working) Paypal module a try  :)
