Reading the Details of Files on the Windows File System

The following function can be added to your Test.user.js file to add support for reading the meta-data for specific files in Windows Explorer. The example below shows the Path, Creation Date, Last Accessed Date and Last Modified Date.

function ShowFileAccessInfo(filespec)
{
   var fso, f, s;
   fso = new ActiveXObject("Scripting.FileSystemObject");
   f = fso.GetFile(filespec);
   s = f.Path.toUpperCase() + "<br>";
   s += "Created: " + f.DateCreated + "<br>";
   s += "Last Accessed: " + f.DateLastAccessed + "<br>";
   s += "Last Modified: " + f.DateLastModified   
   return(s);
}

The filespec parameter is the path (absolute or relative) to a specific file.
