In the past years I've developed some Tools for internal uses. To give you some examples of my work, I placed them here. You may freely use them for non-profit purposes. For other uses feel free to contact me.

Please be aware, that most of them were never intended to go public, so you obviously may miss some useful things like Online-Help, Installers or an attractive User-Interface. They're just useful.

If your File of Interest comes packed as a ZIP-File, just unpack the File into one Directory and start the contained EXE-File (I assume you have a packager like WinZip).

Oops, some necessary legal notes:

I cannot give any Guarantee for the Flawlessness of any Tool here. So you use these Tools at your own Risk and I may take no Liability on any Damage etc. resulting from Execution of these Tools.

You can use all of these Tools without any Fee, but you may not distribute them over any Media, including Web-Sites without my knowledge. If you wish, you may reference to this Tools-Page from your Web-Site (http://www.tofahrn.de/tools/indexe.html), though. Feel free to post any Comments about these Tools to me.
