File Select - Rendering

Rendering

When it comes to the rendering on the screen of a file-select control, there is some variation among web browsers. Typically, on a Windows-based platform, user agents will render a file-select control as a text field, together with a "Browse" button. When the "Browse" button is pressed, a file dialog opens, with which actual file selection on one's platform can take place. After selection, the filename of the selected file is displayed in the text field, with its full path. Alternatively, instead of using the "Browse" button, the filename can be entered directly in the text field.

Some browsers, notably Firefox, no longer allow a filename to be typed directly in. This is a security measure - it is possible to trick the user into uploading confidential information.
