Wildcard file search in WScript - wsh

Question

I need to get all the files in a folder that match a certain wildcard pattern, using JScript. For example:
var fso = new ActiveXObject("Scripting.FileSystemObject");
var folderName = "C:\\TRScanFolder\\";
var folder = fso.GetFolder(folderName);
var searchPattern = "1001-*POD*.*"
// Now I need a list of all files matching the search pattern
I know I could iterate through the folder.Files collection and test the names against a regex, but I would prefer to just get Windows to do a search and get only the ones matching. This is mostly for performance, since there could be several hundred files in the folder, but only a few will be the ones I want.
Is there a function or something that I can use to do a search? Or should I stick with a loop and regex?
Edit: Here I what I got to work with a regex. Is there a way to do it without?
var regex = /^1001-.*POD.*\..*$/i;
var files = new Enumerator(folder.Files);
for (files.moveFirst(); !files.atEnd(); files.moveNext())
{
var fileAttachment = files.item();
if (regex.test(fileAttachment.Name))
{
// Do stuff
}
}

One alternative is to shell out to the command line and use the dir command.
var wsh = new ActiveXObject("WScript.Shell");
var fso = new ActiveXObject("Scripting.FileSystemObject");
var dirName = "C:\\someFolder";
var pattern = "s*";
var fileName;
var oExec = wsh.Exec('%comspec% /c dir /on /b "' + dirName + '\\' + pattern + '"');
// wait for dir command to finish
while (oExec.Status === 0) {
WScript.Sleep(100);
}
// process output
while (!oExec.StdOut.AtEndOfStream) {
fileName = oExec.StdOut.ReadLine();
if ( fso.FileExists(fso.BuildPath(dirName, fileName)) ) {
//do stuff
WScript.Echo(fileName);
}
}
