How do I process all the files in a folder simply?

Question

I need some help with a task I’m working.  I need to access a folder filled with 50+ PDF files and put password protection on each one.  The files will have specific 6-character names and I want each file to always get the same password.  This task would run twice monthly.
                So far I have a working solution with a flaw.  In ADOBE Acrobat professional, I created a separate security policy for each of the 6-character names, assigning each a password.  Using Batch Processing, I run a JavaScript program to password-protect the files.  This process works okay, but the flaw is the need for excess manual processing.  I want the process to spin through the files without any further confirmations from me.  As it is, I have to push the OK button once for every file in the folder.  This is inconvenient.  Is there a way I’m missing to accomplish my goal.
                The script I’m using follows:
/* Applying a Security Policy to a PDF Document */
var ASISecurityAll = app.trustedFunction(
function()
var oMyPolicy = null;
var rtn = null;
var sPolNam = "ASI000";
app.beginPriv();
// First, Get the ID of SimplePassword security policy
var aPols = security.getSecurityPolicies();
var fnm = this.documentFileName;
var fnm6 = fnm.substr(0,6);
var sPolNam = "ASI000";
sPolNam = "ASI" + fnm6.substr(3,3);
for(var i=0; i<aPols.length; i++)
     if(aPols[i].name == sPolNam)
          oMyPolicy = aPols[i];
          rtn = this.encryptUsingPolicy({oPolicy: oMyPolicy });
          break;
app.endPriv();
ASISecurityAll();
Thanks for assistance.

The code shown is straightforward and understandable. If you don't intend to use it in Acrobat 7, you may even replace the loop throgh the policies array using the indexOf() array object method (introduced with JavaScript 1.6, supported in Acrobat 8 and newer), to simplify the code.
According to the documentation for encryptUsingPolicy(), manual interaction may be necessary, depending on the policy used. You might look at the policies if you find ways to reduce interaction.
As an alternative, you might look at third party products which would provide encryption etc. (such as the ones from Appligent, which are command line utilities, and are therefore more suitable to be embedded in a process).
HTH.
