Sometimes, we will request you to send us your project files or samples. You can zip them into a Zip or 7z archive.
Since this forum doesn’t allow .zip attachments, it is possible to upload them to https://wetransfer.com for instance. This is a free file hosting service: after upload, they will give you a URL.
Please send us this URL by Private Mail or copy/paste the URL into your reply, so that we can download the Zip archive.
