Manually installing custom fields

Hello,

I created few custom fields in contacts to suite my purpose. However when I re-install suite crm these fields cause errors. I know that there is an option of taking back up and dumping mysql database to solve this issue. However I want these fields to be installed with suite crm installation itself. Can anyone help me as to where I can find the files that are needed to be modified for incorporating those custom fields in installation of suitecrm? Thank you in advance.

They will be in custom/Extension/modules/Your_Module/Ext/Vardefs/

and then you need to alter the manifest file to copy these files to the this location in installation.
