Uploading all files from Directory to FTP from PowerShell Script

Issue:

     To Upload multiple files from Directory which matches the criteria like '.txt' '.exe' MIME Type.

Solution:

     To read all file from the Directory and uploading one by one. The code will be,
             #we specify the directory where all files that we want to upload are contained
             $Dir=<Path of the Directory>
             #ftp server
             $ftp = <FTP Path>
             $user = <UName>
             $pass = <Passwd>
             $webclient = New-Object System.Net.WebClient
             $webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass) 
             #list every sql server trace file
             foreach($item in (dir $Dir "*.txt"))

            {
                   "Uploading $item..."
                   $uri = New-Object System.Uri($ftp+$item.Name)
                   $webclient.UploadFile($uri, $item.FullName) 
            }
