What will you learn:
In this tutorial we will explain how to only allow specific files to be uploaded. You can restrict unwanted file types from being uploaded (depending on their extension).
To make the file upload with restricted file types, you need to:
Start with an upload page where you have Pure ASP.NET Upload on it. If you haven't done it yet, go through the Simple file upload tutorial.
Select the Pure ASP.NET Upload dialog by opening the Server Behaviors Panel. Select DMXzone - Pure ASP.NET Upload.
When you need to restrict the uploaded files to specific number of extensions, you need to select the Allowed Extensions field.
First choose the extensions type. All means no restriction, Images Only will fill in the most common image extensions and Custom will allow you to enter your own comma separated list of allowed extensions.
In this example we've chosen to only allow our users to upload Images Only.
So now you choose for example to upload Images Only.
Save your page and upload it to your server, and you are done! Go to your website and test it - you should only be able to upload images now.
