How to get List of Folders on Client Machine

There may be the requirement to show all the folders on the Client machine and Server side script will list folders of Application Server.

Html page: we have one Textbox to show and edit folder path.

Two buttons, one for getting the sub-folders and another one to go one level up

---

<input type=”text” id=”txtFolder” value=”c:\” style=”width:250px />

<input type=”button” value=”GetFolder” 

onclick=”javascript:ShowFolderFileList(document.getElementById(‘txtFolder’).value);” />

<input type=”button” value=”Back” onclick=”javascript:back();” />

<ul id=”dvFolder”></ul>

Here is the Script:

<script type=”text/JScript”>

function ShowFolderList(folderspec)

{

var fso, f, fc, s=”;

fso = new ActiveXObject(“Scripting.FileSystemObject”);

folderspec = folderspec.replace(“%20”, ” “);

f = fso.GetFolder(folderspec);

 

fc = new Enumerator(f.SubFolders);

if (fc.item() != undefined)

{

for (; !fc.atEnd(); fc.moveNext()) {

if (fc.item().Path.indexOf(‘$’) < 0) {

path = fc.item().Path.replace(/\\/g, “\\\\”).replace(” “,“%20”);

s += “<LI><a href=’#’ onclick=javascript:ShowFolderList(‘” + (path) + “‘);>” + path + “</a>”;

}

}

}

else

{

s=“No Folder Exists”

}

document.getElementById(“dvFolder”).innerHTML = s;

document.getElementById(‘txtFolder’).value = folderspec;

}

 

function back() {

ctrl = document.getElementById(“txtFolder”);

c = ctrl.value.split(‘\\’);

cval = ctrl.value.substring(0, ctrl.value.length – (c[c.length – 1].length + 1));

if (cval.substr(1, cval.length-1) == “:”)

cval = ctrl.value.substring(0, ctrl.value.length – (c[c.length – 1].length));

ctrl.value = cval;

ShowFolderList(ctrl.value);

}

The above code will show sub folders of the selected folder.
