I have a web part to copy a document (files only not folders) from one
document library to another doc library. I have customize "SharePoint
Context Menus" reference
blogs.msdn.com/bowerm/articles/175691.aspxand added a "copy"
menu. If I select any file, it works but if there is a
folder inside a document library, it doesn't.


So how can I find out whether a selected item is a folder/file? And if it is
a folder, I do not want to display "copy" item in the SharePoint Context
Menu List.

Thanks in advance and here is code of what I have done so far.

-----------------------------------------------
<script language="javascript">

function Custom_AddDocLibMenuItems(m, ctx)
{
var strDisplayText = "Copy";
var strAction;
var strImagePath = "";

var HOST_NAME;
var fileDirPath;
var fileOrDir_Name;
var dotIndex;

HOST_NAME = window.location.hostname
fileDirPath = itemTable.ServerUrl;
//alert("ctx.HttpRoot: " + ctx.HttpRoot);

fileOrDir_Name = fileDirPath.substring(fileDirPath.lastIndexOf('/')+1)
dotIndex = fileOrDir_Name.indexOf('.');

if (fileDirPath != "" && dotIndex != -1)
{
strAction = 'window.navigate("
http://localhost/sites/Site1/default.aspx?query='+fileDirPath+'&host='+HOST_NAME\
+'")';

// Add menu item
CAMOpt(m, strDisplayText, strAction, strImagePath);

// add a separator to the menu
CAMSep(m);
}

return false; // this enables the rest of the menu items to be rendered.
}

</script>
