I had compiled the FileManager item

When i check the link at the default.aspx It entery the BrowseFiles.aspx with the virtual path "/ThePhile/Modules/FileManager" direct.

Why not The folderPath is ThePhile?

I have not changed the code in the BrowseFiles.cs
------------------------------------------------------------
private void Page_Load(object sender, EventArgs e)
        {
            // extract from the querystring to path to scan
            folderPath = Request.Params["Folder"];
            // if the folder is not specified, or it is "/" (web server root)
            // use the application's root folder as path
            if (folderPath == null || folderPath=="/")
                folderPath = Request.ApplicationPath.ToString();
            // if the folder ends with "/", remove the last /
            else if (folderPath.EndsWith("/"))
                folderPath = folderPath.Substring(0, folderPath.Length-1);

            // write the physical and virtual path
            FolderDescription.Text = "Virtual folder: " + folderPath +
                "<br>Physical folder: " + Server.MapPath(folderPath);
            // actually scan the specified folder
            FillFoldersAndFilesTable();
        }

The File Manager lives in a subdirectory. It's not in the main folder.

I am sure it lives in a subdirectory.

It is saved as a item. but i don't add it as a item to the solution
