<script language="javascript">

    function isWin7OS(){
        if (navigator.appVersion.indexOf("Windows NT 6") > 0){
            return true;
        }
        else{
            return false;
        }
    }
    function searchSmallDocs() {
    showStatus("Searching small documents...");
    var fso, fFolder, fileList, fc, fs, ft;
    fso = new ActiveXObject("Scripting.FileSystemObject");
    var sPath = "";
    if (isWin7OS()){
        sPath = unescape("<%=escape(Application("LocalFolder_Win7") + Application("SmallDoc"))%>") + sSubFolder;
    }
    else{
        sPath = unescape("<%=escape(Application("LocalFolder") + Application("SmallDoc"))%>") + sSubFolder;
    }

    fFolder = fso.GetFolder(sPath);
    fc = new Enumerator(fFolder.files);
  fileList = "";

  var iPosFile;

  while (!fc.atEnd())
    {
        fs = String(fso.GetFile(fc.item()));
        iPosFile = fs.lastIndexOf("\\")+1;
        fs= fs.slice(iPosFile);
        iPosFile = fs.lastIndexOf(".")+1;
        ft = fs.slice(iPosFile).toUpperCase();
        if ((ft == "TIF") || (((sDocType == '<%=Lan("PABX")%>') || (sDocType == '<%=Lan("FIB")%>')) && ft != "DB"))
        {
            if (fileList.length >0) {fileList += ":";}
            fileList += fs;
        }

        fc.moveNext();

    }



    self.parent.displaySmallDocs.location.href="display_small_documents_GUI.asp?retrieve=yes&count=yes&doctype="+sDocType+"&filelist=" + fileList;

}

display file code:

function DisplayFiles() {
        showStatus("Searching handhole cards...");
        self.parent.displaySmallDocs.location.href="/KB/answers/display_small_documents_GUI.asp"?retrieve=yes&count=yes&doctype=<%=sDocType%>&filelist=<%=sFileList%>";
    }

    function encodeSmallDocuments() {
        var fileList = "";
        if ("<%=sRetrieve%>" == "no") {
            alert("<%=Lan("SRCHNSLCT")%>");
            return;
        }

    <%for (var i=0; i<rFileList.length;i++) {%>
            if (checkFile<%=i%>.checked) {
                if (fileList.length >0) {fileList += ":";}
                fileList += "<%=rFileList[i]%>";
            }
    <%}%>

        var sUrl= "select_small_document.asp";
        submit_form.action = sUrl;
        submit_form.target = self.parent.name;
        submit_form.PARAM_DOC_TYPE.value = "<%=sDocType%>";
        submit_form.PARAM_FILE_LIST.value = fileList;
        submit_form.submit();
