Hi,
So from what I understand, what you want is to automatically populate the downloadable files in the products of your HikaShop from the data of VirtueMart for the corresponding products.
I think it should be possible with a bit of work.
We would need:
- a FTP access
- a database access
- a backend access
- the folder path where the files are stored for VM
We can discuss this further via email. Please reach us via our contact form with a link to this thread for refence:

Regarding the size of the files, it's not a problem. The upload limit will just limit you if you want to upload new files via the interface of HikaShop. And that limit is not in HikaShop. It's the limit of your hosting (usually configured in the php.ini). Sometimes, you can even change it yourself if necessary
