Using FTP script and rename files at client

[mydisney]

I have a ftp script that connects to a client site and picks up files using wild card like *.asc. I need to use wild card since files that are placed in the folder are dynamically named based upon date and time. This works fine. Next thing I need to do (in the ftp script) is either 1. rename all files to a different extension or 2. move them to a sub directory so I do not pick them up again. Can anyone give me some cluse how to do this please. I have tried to use wild card in the rename command but it does not rename unless I explicitely name the file and the extension.

Set objMyFile = objFSO.CreateTextFile(strFTPScriptFileName, True)
objMyFile.WriteLine ("open " & strFTPServerName)
objMyFile.WriteLine (strLoginID)
objMyFile.WriteLine (strPassword)
objMyFile.WriteLine ("cd " & strFTPServerFolder)
objMyFile.WriteLine ("bin")
objMyFile.WriteLine ("lcd " & strLocalFolderName)
objMyFile.WriteLine ("prompt")
objMyFile.WriteLine ("mget " & strFilePut)
objMyFile.Writeline ("rename " & "/*.sav" & " " & "*.asc")
objMyFile.WriteLine ("disconnect")
objMyFile.WriteLine ("bye")
objMyFile.Close
