The Foldertree application you have been referred to was built by the previous owners of the domain on which this site is now hosted. Essence Media Ltd is not in any way connected with any of the developers of Foldertree past or present, but a copy of the original application is available here for download. We've also included a brief history of Foldertree below, so that all those involved in its development are acknowledged.
This was rewritten by Marcelino Martins to take advantage of the emerging DHTML capability of Internet Explorer and Netscape Navigator browsers, so that as nodes were collapsed or expanded, the relevant parts of the tree were made visible or invisible. This became version 2. This supported version 4 or later of Internet Explorer or Netscape Navigator.
Towards the end of 1998, Nigel Goodwin of Essence Associates Ltd. re - architected version 2 the Folder Tree script to greatly improve performance for large trees. This, in some cases, resulted in performance improvements of over a hundredfold. Some features were available, but not documented, so were only used by the author.
At about the same time, Roger Bedard of CompSolutions-CSI (http://www.CompSolutions-CSI.com) also modified version 2, and added many options to allow much more configurability to the style, and look and feel, of the script. This became version 3e.
It became clear that a version of folder tree which combined the performance improvements and the greater configurability of the look and feel would be a very useful product which could be widely used It also became clear that, if the script was to be widely used, a significant amount of effort would be needed to support and promote it, as well as continue to enhance it.
Essence Associates therefore, with the support and cooperation of Marcelino Martins and Roger Bedard, decided to produce the first commercial release, version 4, which combines the best features of previous versions. This was released in March 1999.
In addition to the previous performance improvements, and the look and feel improvements, this version 4 of folder tree also provided support for version 3 or later of Internet Explorer or Netscape Navigator (whilst transparently taking advantage of DHTML capabilities of later versions), corrected various bugs, added a few extra look and feel features, and was designed to be fully supported and documented.
