In the cmdUpload_Click, you can add a check on the filename to see what kind of file you are uploading

Asp.Net has a limitation on the size of file being uploaded. You can override it by setting the reqd size in web.config. For eg: If you want to set the upper limit to 10mb, use the following entry in your web.config.
