Moving OpenCart Extensions - opencart

Question

I have an old OpenCart set up but not the extension source files.
I need to copy all OpenCart extensions from my first installation to a new one.
Both OpenCart installations have the same version. The extensions include some vQmod scripts as well.
Open Cart installation has multiple extensions installed. We have to move them to another open cart store.
We do not have the zip files for extensions so we can not find out which files we have to move for each extension.
is there any way to identify the files for each extension or download them from the first opencart setup ?

Answer 1

admin(remove config.php)
catalog
download
image
system
vqmod
index.php
copy all files to your new opencart excpet the config.php and admin/config.php

Answer 2

which openCart version you are using???
Actually there is no way to find it automatically But there is a way manually but it took too much time
compare your exiting opencart version files with same version default opencart files(Remaining Files are your Extension Files )Here you can find defaul OpenCart versions Files, Download and compare with your relevant version
Secondly go into Admin side there in modification there you will find modification log there you can find where and to which files to some specify extent-on are effected For Example
