This function imports folders and their contents, creating ideas with text, images and documents.

The folder import dialog is made of three parts, describing the files suffixes to consider (not mentionned file types are ignored) : 

1. File types to import as ideas : WIT renders these files as ideas which text is the file contents.
2. File types to import as images: WIT adds references to theses files in the current idea list of images (the images will be shown in the idea).
3. File types to import as documents : WIT adds references to theses files in the current idea list of local documents.

The "Include sub folders" option recursively adds current folder sub folders.

The "Make image album" option change the import behavior for imported images : WIT creates an idea for each image (wherever the image file suffix is speficied), and creates thumbnails of images in every folder containing images.

Use both option to recursively create image albums.

WIT creates at least as many ideas (nodes) as encountered folders.

You can save and restore the import folder parameters, with *.fif files (folder import format).
