Most software packages written for Windows have an uninstall facility. However, there is no easy way to delete files that may already be open. The purpose of WipeDir is to facilitate the development of uninstall methods for small applications by allowing directories containing open files to be deleted as cleanly as possible.
The typical problem when uninstalling an application called GeeWhizz is that because the uninstall program itself is open (/program files/GeeWhizz/uninst.exe) it prevents the directory from being deleted. In this instance, provided the file wipedir.exe is located in the GeeWhizz directory, removal of the directory is achieved by the command wipedir /self.
