Thank you very much. Do you have any idea that before uploading file we can calculate its total space and check it with our limited space like 50MB. if it is less then upload if it is not then show message.... if you know about it then please share.. Thanks in advance

To upload multiple files from different sources : We can browse or select files one by one and store their paths in the collection and loop through the collection and upload them on a single click. Before we get into the code I want to quickly go over some things that may or may not be new to you. First, System.Web.HttpFileCollection: this class "Provides access to and organizes files uploaded by the client" - essentially, it contains a collection of HttpPostedFile classes and is access through the System.Web.HttpConext.Current.Response.Files property. The second thing used is some static methods of the System.IO.Path class: The GetFileName and GetExtension methods are used. The GetFileName method will retrieve the file name and file extension from a path. The GetExtension method does exactly what it sounds like it should do. It gets the file extension from a file. A Sample code mentioned below is based on the assumption that file upload control is being used for the purpose. private Boolean SaveImages() { //loop through the files uploaded System.Web. HttpFileCollection _files = System.Web. HttpContext .Current.Request.Files; try { for (System. Int32 _iFile = 0; _iFile { System.Web. HttpPostedFile _postedFile = _files[_iFile]; System. String _fileName, _fileExtension; _fileName = System.IO. Path .GetFileName( _postedFile.FileName); _postedFile.SaveAs( System.Web. HttpContext .Current.Request.MapPath( "FileUploads/" ) + _fileName); } return true ; } catch (System. Exception Ex) { return false ; } } Another approach is : 1. A windows application that selects multiple files and upload them at once(using FTP commands) can be developed. 2. This windows application(that resides on the web server where asp.net application is loaded), when user “Add/Upload Multiple Files” this application is downloaded on the client machine and installed automatically on the client machine. 3. This application will then be used to upload multiple files at once.
