  • Free space is dynamically calculated based on the total size of files in the virtual file system.

Changes the current directory to the specified directory.

• Usage:

  cd <directory>
  

• Example:

  cd projects
  

• Notes:

  • You can use this command to navigate between different directories in the virtual file system.

Opens and edits HTML files using a built-in editor that features a toolbar for common HTML operations such as bold, italic, headings, and links. You can create new files if they don't exist.

• Usage:

  ckcode <filename>
  

• Example:

  ckcode index.html
  

• Editor Features:

  • Toolbar buttons for common HTML tags (e.g., bold, italic, headings).
  • Files are saved back to the virtual file system, and optionally to localStorage.

Reads and displays markdown (.md) files in a floating modal window. The markdown is rendered as HTML for easy reading.

• Usage:

  read <filename>
  

• Example:

  read manual.md
  

• Notes:

  • This command opens the file in a modal window, and the markdown content is rendered into HTML.

Views images or videos in a floating modal. Supported formats include .webp for images and .mp4 for videos.

• Usage:

  view <filename>
  

• Example:

  view example.webp
  

• Notes:

  • This command displays the image or video in a floating modal window for easy viewing.

Renders HTML files in a floating modal window as a preview, simulating how the HTML would appear in a web browser.

• Usage:

  browser <filename>
  

• Example:

  browser index.html
  

• Notes:

  • This command is useful for previewing how HTML files will render in a browser without leaving the command-line environment.

Formats the C: drive. This command supports a full format, which takes 5 minutes, or a quick format with the /q switch, which takes 15 seconds. After formatting, the user is prompted to enter a new volume name. During the format process, user input is disabled.

• Usage:

  format C: [/q]
  

• Options:

  • /q: Quick format (15 seconds).

• Example:

  • Normal Format:

    format C:
    

    • Simulates a full format taking 5 minutes.

  • Quick Format:

    format C: /q
    

    • Simulates a quick format taking 15 seconds.

• Process:

  • Step 1: During the format, input from the user is disabled.
  • Step 2: A progress bar and status updates simulate the formatting process (e.g., "Writing tables...", "Lining up dominos...").
  • Step 3: After the format is completed, you will be prompted to enter a new volume name.
  • Step 4: The system resets the file system and reloads from filesystem.json, clearing local storage.

• Version Tracking: CKOS includes version tracking, which is stored in settings.json. You can view the current version using the version command.
• Local Storage: CKOS uses local storage to persist files. The format command clears local storage and resets the file system to its initial state.
• Floating Modal Windows: Many commands, such as read, view, ckcode, and browser, open content in floating modal windows for a dynamic and modern interaction experience.

This manual now includes the updated functionality such as the version command, formatted file sizes, and the enhanced behavior of the format command with user interaction.
