selling .epub files via woocommerce to be downloaded from google drive

Hi,

Thanks for contacting us here about this extension.

Please I'd like to securely sell .epub files via woocommerce to be downloaded from my google drive.
Is it possible with you guys?

Yes, you can sell any files from your cloud (Google Drive) in WooCommerce as your local files.
And it's completely secured because the file access is strictly limited by the cloud API connector.

If so, is there any size limits?

There is no limitation here, files are acutally stored at Cloud server.

Hope it helps!
Kind regards,
