How to get rid of hidden folders

Hi,

I need to report if the link folder contains any subfolder or not. The below coding is working fine but in some files it shows some folder names but when i see the parent link folder then it is not visible. How to ignore the hidden folders. Is it the method i used is correct? Because some times it show the result wrongly.

var inputFolder = Folder(app.activeDocument.allGraphics[0].itemLink.filePath).parent;
var fileList = inputFolder.getFiles(); 
var myArray=[]
flag=0;
for(i=0;i<fileList.length;i++){
var myfile=fileList;
    if(myfile.name==".DS_Store") continue;  
    if((myfile instanceof Folder) && (!myfile.hidden)){
        myArray.push(myfile);
        if(myArray.length>0){flag=1;}
    }
}
if(flag==1){alert("ERROR: Some SubFolder(s) present in the Link Folder. "+ "Name and Path of SubFolder(s)\n"+decodeURI(myArray.join("\n")))}
if(flag==0){alert("No SubFolder(s) present in the Link Folder")}

Also is it any other method we can use to achieve my need?

Thanks,

K
