Is there a way to show only .xxx files in the default file chooser dialog. xxx may be not-known file types, such as abc, efg etc.
I'm using html5 so it may have new support for this type of things.
Thanks!
The HTML 5 accept attribute on file input elements is for this purpose. E.g.:
<input type="file" accept=".doc,.docx,.xml,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document">
