CCK Importer | drupal.org

This module provides an easy way to import previously exported CCK definitions.

1. Export the content types you wish to import and paste the exported text into separate text files (name and extension not important).
2. Place the newly created text files in the /import subdirectory of this module.
3. Ensure all dependant modules are installed for the fields in the content types.
4. Install the module.

The idea is that you could have a collection of commonly used content types in a folder. Then, when you start a project, copy the required content type definitions into this module and install. This will create all the content types in one go, saving you from using the CCK import form provided by content_copy.module.

If you are happy with using the import form provided by content_copy.module then you don't need this module. This is very small module that just makes it easier to install content types from previously saved text files.
