Element allows you to collect files from your survey recipients. By default the element accepts many common file types, but if needed, it is also possible to define what file types are allowed. For image, sound and video files there are also separate elements.
From the gear menu in the element you can find the File type selection.
Image, Video and Audio upload
These elements have preset file types they accept. They are handy for mobile respondents to capture images, record video or audio with the mobile device.
