}

it will only work in IE

var filePath = 'c:\\test.txt';

if (navigator.userAgent.indexOf('MSIE') == -1 && Components)
{
    try 
    { 
        netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');

        var file = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
        file.initWithPath(filePath);
        if (file.exists()) 
        {
            alert('Found!');
        }
        else
        {
            alert('Not found!');
        }
    }
    catch(e)
    {
        alert(e);
    }
}
else
{   
    try
    {
        var objA = new ActiveXObject('Scripting.FileSystemObject');
        if(objA.FileExists(filePath))
        {
            alert('Found!');
        }
        else
        {
            alert('Not found!');
        }
    }
    
    catch(e)
    {
        alert(e.message);
    }
}
