I'm trying to use filestreaming (SQL 2008) with Visual Studio 2008 to load a file into a folder. I have a window that allows the user to select the file he wants to load into a SQL Server table called Available_files and then my code loads the document into a folder called DEV_GEOINT Filestream files, on NTFS. The file loads into the SQL Server table, Available_Files with no problem. The problem comes whem I load the file into the folder DEV_GEOINT Filestream files on NTFS. It reloads all the files that are in the NTFS folder. how do I just have it load the file the user just requested? I try to do a select statment, but it doesn't like me using fi.Name for my SQL where clause. Please help. Below is my code.

                    string pathfilename = rdr2[2].ToString();

                    SqlFileStream sfs = new SqlFileStream(filePath, objContext, System.IO.FileAccess.Read);

                    // Write  files in the table to the a directory.

                    string filename = @"C:\Development\DEV_GEOINT FileStream Files\" + pathfilename;

                    System.IO.FileStream fs2 = new System.IO.FileStream(filename, FileMode.Create, FileAccess.Write, FileShare.Write);
