You can use http://www.berezniker.com/content/pages/visual-foxpro/file-operations-progressbar to remove a folder (including subfolders and files, if any).

lcFolder = "H:\temp\MyFolder"
IF FileOpWithProgressbar(lcFolder, "", "Delete")
  * Folder removed
ELSE
  *  Error
ENDIF

>Background: I need to create and remove directories in a temp folder. Creating and removing is NOT the problem
>
>The problem comes in if someone is sitting in the directory to be removed. VFP cannot remove the directory and I'd like to catch that and report it.
>
>Question: does RmDir return anything? Since it's VFP 6, no Try..Catch block :-(, and if I have to do the whole "Save Error Routine, On Error, Reset back to old Error", I will - I was just hoping that it returned something I could catch easily.
