Note: ZFS is unstable and I would use with caution, there are a few issue with updates and large file support. I've proved the theory and any patches are gratefully accepted. Its also been found to totally corrupt all the objects in your ZODB. If you use this you might want to toss your ZODB after!!!
ZFS allows you to represent standard Zope objects on the file system in an easy editable form without all that mucking about making extra objects. You can create, edit and update standard zope objects from the file system. Use all your favourite tools for building Zope apps.
Warning: ZFS is in development, do not use for anything important.
Objects currently supported: Folders, Images, DTML Methods, DTML Documents, Page Templates, Python Scripts and Files. For more information see using ZFS.
