The file input type is used to identify resource(s) in the file structure, upload a file, or create a resource to upload.
The file input element provides a GUI to select a file, and then represents a list of files that are selected with the option to change resource(s) until form submission.
The multiple attribute allows more than one resource to be selected. Some browsers will add an "s" to their no file is selected message if this attribute is present.
The accept attribute provides a hint of what file types the server is able to accept. Adding capture on some devices will allow the user to capture a video, audio or image files with the devices camcorder, microphone and/or camera.
Of the input types, the file input type varies the most between browser, and is not very stylable.
Messages vary: Firefox and IE both use "browse", while Safari, Chrome and Opera employ "Choose File", or "Choose Files" if the multiple attribute is present.
Firefox, Safari, Chrome and Opera indicate the name of the file next to the button if only one file was selected, with Safari including an icon indicating file type.
If more than one file was selected in the case of multiple, "X files" is listed, with X being the number of files selected.
IE shows the file name including the full path to that file. In case of multiple files, it presents all files in a scrollable text input.
