3. File Naming Conventions

Files are identified by a filename, which often consists of two parts:

• Root Name: User-defined descriptor (e.g., report, image001).
• Extension: A suffix separated by a period (e.g., .txt, .pdf, .exe). The extension typically indicates the file format or associated application.

Examples:

• budget.xlsx → Excel spreadsheet.
• script.py → Python source code.
• family.jpg → JPEG image.

File Encryption

Encrypting a file transforms readable data into ciphertext. Even if a hacker steals the hard drive, without the key, the file is gibberish. Root Name: User-defined descriptor (e

• Windows: Use BitLocker (full drive) or EFS (per file).
• Mac: Use FileVault (full drive) or create an encrypted disk image (.dmg).
• Cross-platform: Use VeraCrypt for encrypted containers or 7-Zip (with AES-256) for individual compressed, encrypted files.

Yet, despite their constant presence in our daily lives, few people stop to think about what a file actually is, how it works, or the invisible system that keeps them all organized. Examples:
