This program came out of my need

This program document all the projects files.
Project files are documented as per file mask.
Save their names to a database later on to
update the files.
With the files, one adds a description including project
pictures, category, and name.
Before saving add categories.
Categories are written to a tree.
The project category (which is a tree) is added like this
name>name>… name> to the database.
This program does not save the files only their names and date-time.
Print the database records to PDF or HTML.
