Add an action to import zip files.

Project description


MassLoader allows to do massive uploads via Zip or 7Zip files. When an archive is uploaded via MassLoader, its contents are created in the current folder.


  • MassLoader creates Files and Images or only Files with files in archive.
  • MassLoader add an action on Folder, Large Plone Folder and Plone Site. You can change theses portal types in the control panel.
  • MassLoader has a content size limit, and is able to protect your server from logic bombs.
  • MassLoader can handle any size of archive file, without overload of your server.


  • The permission is only set by default to the role ‘Manager’ and ‘Owner’.
  • From the version 3.0.0beta1, the portal type of new object can be managed via 2 mechanisms, selectable in the control panel :
    • If content type registry detects an Image, MassLoader creates an Image, if it’s not an image MassLoader creates a file with the portal type selected in Control Panel.
    • Or the checkbox is checked in Control Panel and Massloader creates only files with the portal type selected in Control Panel/
  • Default max size for each file to be uncompressed is set to 20 Mb. You can modify this size limit in the control panel.
  • If a folder with a same id already exists, it is conserved. If a same file exists whith the same id, just the datas are updated.


  • 7zip archives are not valid when they contain only empty folders (problem with python library pylzma).
  • 7zip archives with empty folders : the empty folders are not created.
