Hi, If you only looking to upload files in asp.net then you have the control called file upload. This is control which allows you to select the file in your computer to see all the drives, directories and files. After selecting the files and click on another button something called "Upload", you need to write the server side code. protected void btnUpload_click(object sender, EventArgs e) { FileInfo fileInfo = new FileInfo( fileUpload.PostedFile.FileName); if(fileUpload.HasFile) { fileUpload.PostedFile.SaveAs(Server.MapPath( fileInfo.FileName)); } } The above will be saved into your application folder.
