Folder SIZE - full Delphi source

Folder SIZE uses a TreeView component to display the folder sub-directory structure (where each node stores an object using linked lists with pointers). The standard approach to file searching along with threading makes it super fast. A simple "Browse For Folder" dialog is displayed using the RTL's SelectDirectory function.

Folder SIZE can be extended with new ideas; here are some you can add to the code: run as a shell extension, more charting options, file filtering.

Feel free and encouraged to add any of the new features to Folder SIZE. Send me your version of Folder SIZE, I'll be happy to make it available to others here.

If you need any help with the code, be sure to post your questions on the Delphi Programming Forum.
