Script to save previously unsaved, newly created files?

Question

I'm looking for a script that can save an open, previously unsaved, image as a TIFF file.
It's important that it's not needed to enter a new file name every single time the script is executed, I need the script to do that for me, at least once a file name is pre-defined in the script.
The script must also automatically "number" the files like file0001.tif, file0002.tif,, file0003.tif, etc., in order to not overwrite an already existing file.
Is there a script that fits my description?
Cheers!

Please try this, you will have to edit the script to meet your needs.
It will save ALL open documents an close them once saved.
#target photoshop
app.bringToFront();
main();
function main(){
if(!documents.length) return;
//amend to suit
var folderPath = Folder("/c/folderName");
if(!folderPath.exists) {
    alert("Output folder does not exist!");
    return;
//this should be the first part of the filename
//I.E. if file name = Picture0001.tif it needs to be Picture
//N.B. it must be the same case!
var fileName  = "filename";
var fileType = "tif";
while (documents.length) {
var fileList = new Array();
var newNumber=0;
var saveFile='';
fileList = folderPath.getFiles((fileName + "*." + fileType));
fileList.sort().reverse();
if(fileList.length == 0){
saveFile=File(folderPath + "/" + fileName + "0001." +fileType);
SaveTIFF(saveFile);
activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}else{
newNumber  = Number(fileList[0].toString().replace(/\....$/,'').match(/\d+$/)) +1;
saveFile=File(folderPath + "/" + fileName + zeroPad(newNumber, 4) + "." +fileType);
SaveTIFF(saveFile);
activeDocument.close(SaveOptions.DONOTSAVECHANGES);
function zeroPad(n, s) {
   n = n.toString();
   while (n.length < s)  n = '0' + n;
   return n;
function SaveTIFF(saveFile){
tiffSaveOptions = new TiffSaveOptions();
tiffSaveOptions.embedColorProfile = true;
tiffSaveOptions.alphaChannels = true;
tiffSaveOptions.layers = true;
tiffSaveOptions.imageCompression = TIFFEncoding.TIFFLZW;
activeDocument.saveAs(saveFile, tiffSaveOptions, true, Extension.LOWERCASE);
