You can save the files only in subfolders of your web application. This is an example of valid path: "~\MyFolder" and means the folder ""MyFoloder" from my web application root.if (filUpload.PostedFile != null) { string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(filUpload.PostedFile.FileName);string fileExtension = Path.GetExtension(filUpload.PostedFile.FileName);filUpload.PostedFile.SaveAs(Server.MapPath(savepath + "/" + fileNameWithoutExtension + fileExtension)); }It's working fine..
