How do I save a file using javascript as a different name if file already exists?

How do I save a file in Acrobat Pro 10 using javascript as a different name if file already exists?

I have a javascript that is run when a button on a form is pressed. The javascript saves the file based on field names. Now I would like it to not overwrite if a file is already save with the same name. I would like it to just add an 1 to the end of the file name and then incrementally increasing.

the javascript:



// Get the field value
var fn = getField("Job Name").valueAsString + "_" + getField("Bill to").valueAsString + "_" + getField("Invoice#").valueAsString + "_Exported";
// Specify the folder
var fldr = "/c/PATHNAME/Exported/";
// Determine the full path
var fp = fldr + fn + ".pdf";
// Save the file
myTrustedSpecialTaskFunc(this, fp);

Thank you for any assistance.

Unfortunately, this cannot be done. For security reasons Acrobat JavaScript is sandboxed, meaning that is only has controlled, and weak, connections to the outside world. It cannot test for files in the file system.

Having trouble, Why Doesn't my Script Work

Actually, it is possible, but only if the other file is disclosed.
In that case you could try to open it using app.openDoc() and check if the result is null. If it is, you know there's no file with that name (or there is, but it isn't disclosed). If it's not null, you know there a disclosed file with that file name.
What you can do is add a script that discloses the files before you save them, to make sure that you'd be able to find them the next time you run the script.

Were you able to figure out how to do this? If so, can you provide an example script?
