Contentstack End User Training (EUT)
File Field
The File field enables users to upload and use files in an entry.
When you add this field to the content type, it shows the following options:
Choose a file - This lets you select an existing file(s) stored under ASSETS.
Upload a new file - This lets you upload any file from your local system.
Every file you upload via the Upload new file option gets stored as an asset in Contentstack.
