Create dynamic directory name from form field on Sharepoint

Question

Trying to save pdf file to sharepoint site using URL; but need to create directory (initially) and filename dynamically. After directory created addtn'l files may populate dir, so need to check for directory exists; if so just copy files to dir based on field name. I'm able to save files to hard-coded location only, based on below.
How to check and/or create dynamic directory base don field name?
// folder level JavaScript to allow access to the identity object properties
trustedIdentity = app.trustedFunction( function (sProperty)
var iProperty = "";
app.beginPriv();
iProperty = identity[sProperty];
app.endPriv();
return iProperty;
// folder level JavaScript to allow Save As population of file name
mySaveAs = app.trustPropagatorFunction(function(myForm, path)
     app.beginPriv();
     var myForm = event.target;
     return rtn = myForm.saveAs(path);
     app.endPriv();
myTrustFunct = app.trustedFunction(function(myForm, path)
     app.beginPriv();
     var vTest1 = event.target.xfa.resolveNode("topmostSubform[0].Page1[0].Test1[0]").rawValue.toString();
     var vTest2 = event.target.xfa.resolveNode("topmostSubform[0].Page1[0].Test2[0]").rawValue.toString();

Acrobat/Reader cannot create a directory. The directory needs to exist before Acrobat/Reader can save a PDF file to that directory.
You could create a plug-in and use that plug-in to create the directory. The plug-in should also be able to determine if the directory exists or not.
SharePoint can be tricky because it is not like most web sites. There is a special dash board that helps manage the different parts of SharePoint like list, folders, web parts, documents, etc so you may need to be aware of these features and adjust for them.
For  folder level functions, I would not use any LiveCycle JavaScript variations. The folder level scripts are shared and accessible by Acrobat forms.
