Blue File Folder Icon Design

This illustration showcases a contemporary file folder icon, rendered in a sophisticated dark blue-grey with a subtle metallic sheen. A distinct, large 'X' symbol is centrally placed on its front, giving it a unique identity. The design is sleek and modern, utilizing light and shadow to create a sense of depth. It evokes a sense of organization, system files, or perhaps a specific application or operating system folder.
