How to cleanup Extensions in filesystem?

[henrikfalk]

Hi

My first Java extention is almost ready. The core functionality is working

During the development I made many deployments of my extension that creashed OpenOffice. When I open the extension Manager it is a complete mess because even though I deleted my extension there seems to be some leftovers in the Extension dialog.
Some of the extensions have links pointing to my website!

Does anyone know of a tool that is able to clean up the filesystem where openOffice keep its extension data?
Or where is the information kept on a Windows XP/Vista installation?
And how do I safe delete leftovers of my extension?

Regards
Henrik
