A file stores information, while a folder groups files and other folders. A path describes where an item is located in a filesystem. Understanding this structure makes it easier to find work and avoid editing the wrong copy. A filename usually includes a name and an extension, such as .txt or .jpg. The extension is a convention that helps software identify the format; renaming it does not convert the contents. A path may be absolute, starting from a defined root, or relative to the current location. For a project, separate source material, working files, and final outputs with descriptive names. Avoid names like “final-final-new” that conceal version history. Before moving or renaming a file, consider whether another document or program refers to its path. Practice: Draw a folder structure for a small learning project. Explain where an original image and an edited copy belong, and how their names distinguish them.
