ZipFolder is a folder,
plus:
- manage_upload(Form) to upload a zip file
The zip file's content will be used to
create Document/File/Folder/Image objects inside the
folder
- manage_addZipFolder accepts an optional zip file,
to upload a zip file directly
minus:
- doesn't create index_html or acl_users in constructor
Some problems still exist:
- zipfile.py doesn't handle all zipfile formats yet
- zipfile.py of Python 2.0 is broken
- zipfile.py for Python < 2.0 does not exist
If you are using Python 1.52, or experiencing problems
unpacking zip files with Python 2.0, copy zipfile152.py
in this package to zipfile.py.
This is a modified version of the Python zipfile.py (release 1.11
or later):
- it requires zlib to run on python 1.52
- it contains a fix for a file header problem (fixed in Python 2.1)
- doesn't seem to work with zope-win32 (binary distribution)
