Rename the opening file & then open it

Question

Hi,
I am looking for a script which can -
1. On opening a file rename it. For e.g. Rename "FileName1.indd" to "FileName1-in-use.indd"
2. Then open the file "FileName1-in-use.indd"
3. Then on closing rename it back to "Filename1.indd"
Is it possible?
Regards

Hi there
I am not sure if this meets your needs. What about «race conditions»?
Give this a try.

main();
exit();
function main() {
    var myDoc = File.openDialog ("InDesign-File", fileMaskINDD);
    if (myDoc != null) {
        // get the actual filename
        myFileName = myDoc.name.substr(0, myDoc.name.indexOf("."));
        myNewFileName= myFileName.replace(myFileName, myFileName+"-in-use.indd");
        // rename the actual doc
        myDoc.rename(myNewFileName);
        // open the InDesign document
        tempDoc = app.open(myDoc);
        // do your stuff here
        do_your_stuff_here(tempDoc);
        // save and close
        tempDoc.save();
        tempDoc.close();
        // rename the document again
        myDoc.rename(myFileName+ ".indd");
        alert("I did my job, what about yours?");
function do_your_stuff_here(myDoc) {
    alert("Do your stuff here");
    To filter the files and only show InDesign files or directories
function fileMaskINDD(myFile) {
  if (myFile.constructor.name == "Folder") { return true }
  if (myFile.name.slice(-5) == ".indd") { return true }
  return false;
