Best Practices in File Management

Effective file management in software development ensures organization, maintainability, and efficiency. Here are the key principles:

• Folder Structure: Organize files logically based on purpose (e.g., src/, tests/, assets/).
• Naming Conventions: How you name files, folders, variables, and functions communicates the purpose of each component and keeps code readable across a team. How to name or identify variables in programming is often an organizational specific preference. As a general rule:
  • Use names that are as short and as meaningful (semantic) as possible.
  • Do not use spaces or special characters. Use a recognized naming convention instead.

  Common Naming Conventions in Programming

  • Camel Case — Each word is capitalized except the first.

    julySales, getNewReport()

    Commonly used in JavaScript, Java, and C# for variable and function names.
  • Pascal Case — Every word is capitalized.

    JulySales, GetNewReport()

    Commonly used in C# for class names and in React for component names.
  • Snake Case — Words are separated by underscores.

    july_sales, get_new_report()

    Commonly used in Python and Ruby for scripts and module names.
  • Kebab Case — Words are separated by hyphens.

    july-sales, get-new-report

    Commonly used in CSS and HTML for class names and IDs, and for static file and folder names.

  "Whenever you develop code in a new language, get comfortable with the variable naming conventions and always check with your team if your organization ever deviates from the standard. It will make your code more readable and help your code blend with all of the code commits, pulls and merges." – theserverside.com

  Each course or discipline may apply these conventions in specific ways. For example, WDD 231 establishes clear expectations for file and folder naming in web projects: WDD 231 Naming Conventions.

• Modularization: Break large files into smaller, focused files where each file has a single, clear responsibility. For example, keep CSS, JavaScript, and HTML in separate files rather than mixing them together. In a JavaScript project, separate utility functions, data fetching, and UI logic into their own modules. Smaller files are easier to read, test, debug, and reuse across a project.
• Use Effective Version Control: A version control system like Git records every change to your project so you can revisit any previous state, collaborate safely, and understand why each change was made.
  • Commit frequently with short, meaningful messages that describe what changed and why. Use an imperative verb to start the message.

    git commit -m "Fix: Correct validation on user input errors"

    Avoid vague messages like "update" or "stuff" — they make it hard to trace problems later.

  • Ignore unnecessary files: A .gitignore file tells Git which files and folders to exclude from the repository. Never commit dependency folders, build output, or secrets.

    node_modules/
    dist/
    .env
    logs/

    Most project generators provide a starter .gitignore. Review it before your first commit.

  • Use branches: Create a new branch for each feature or bug fix. This keeps the main branch stable and makes code review straightforward.

    git checkout -b feature/add-login-form

    Merge back to main only after testing and review. Delete the branch once it is merged.

  • Write a README: Every project repository should include a README.md at the root explaining the project purpose, how to set it up locally, and how to run it. This file is the first thing collaborators and instructors see.
• Automate Repetitive File Management Tasks: Using linting and formatting tools help keep code readable and usable. Automate backup and cleanup scripts and use build scripts to generate distribution files.
