Folder Structure Diagram: tree-like utility for generating ASCII folder structure diagrams. A folder diagram summarizes structure for documentation without requiring readers to inspect an entire repository or archive. Formatting changes the presentation of structured text so that people can inspect and maintain it more easily. The target language or application still determines whether the result is valid and what it means. Keep a copy of the original and compare the output before replacing configuration or command text, especially where quoting and whitespace have special meaning. A small sample containing comments, nested structure, and quoted values is a useful first test. After formatting, use the destination program’s own syntax checker or preview to confirm that the resulting document behaves as intended.

How to use this tool

1. Begin with a representative input. For a practical test, use: A small folder list containing src, assets, and README.md. Replace demonstration values only after you understand the output.
2. Paste a representative source sample and select the formatting options exposed by the tool, preserving significant quoting and comments.
3. Compare the formatted result with the original, checking nested structure, escaped characters, and any whitespace that has semantic meaning.
4. Validate the result with the destination application or its syntax checker before replacing a working configuration or script.

Include only meaningful levels and avoid placing private directory names or user-specific paths in public documentation.

Treat layout characters as part of the content

ASCII lettering, image approximations, and folder trees communicate through the positions of characters. Spaces and line breaks are structural, not disposable formatting. Preview in the final font and width, and protect the result with a preformatted or code block when the destination supports one. Avoid automatic typography changes that replace or collapse the characters used for alignment.

Choose detail appropriate to the medium

A wide banner can overwhelm a terminal, a detailed image can become unreadable at narrow widths, and a deep folder tree can obscure the important structure. Simplify until the result communicates at the intended size. Keep a plain descriptive alternative where accessibility or search matters. For folder diagrams, document meaningful structure without accidentally exposing private or machine-specific paths.

When this tool is useful

• Document a project layout
• Explain an archive structure
• Prepare onboarding notes

Tips for a better result

• A diagram documents the supplied structure; it does not create directories or verify that those paths exist.
• Readable formatting is helpful for review but is not evidence that a configuration is operationally correct.
• When whitespace is significant, inspect the source characters as well as the rendered appearance.
