>How can we programably rename a folder in vfp8?

You can use MoveFile Win API or WSH

lcOldFolder = "h:\tmp\testdir"
lcNewFolderName = "TestDirNew"

* Win API
DECLARE Long  MoveFile IN WIN32API ;
	String SourceFileName, String DestFileName
IF MoveFile(lcOldFolderName, lcNewFolderName) = 0
  * Rename unsuccessful
  ...
ENDIF

* WSH
oFSO = CreateObject("Scripting.FileSystemObject")
oFolder = oFso.Getfolder(lcOldFolderName)
oFolder.Name = lcNewFolderName
