1. What is Disk Space Calculation?

Disk space calculation helps you determine how much storage is being used on your Mac by subtracting free space from total space. This is essential for storage management and preventing disk full errors.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( Used \) — Space used (GB)
• \( Total \) — Total disk capacity (GB)
• \( Free \) — Available free space (GB)

Explanation: This calculation shows how much of your disk's total capacity is currently occupied by files and applications.

3. Importance of Disk Space Monitoring

Details: Regular disk space monitoring helps prevent system slowdowns, ensures proper functioning of applications, and helps with storage planning.

4. Using the Calculator

Tips: Enter total disk capacity and free space in GB. Both values must be valid (total > 0, free between 0 and total).

5. Frequently Asked Questions (FAQ)

Q1: How do I find total and free space on my Mac?
A: Go to Apple menu > About This Mac > Storage, or use 'df -h' command in Terminal.

Q2: What's considered low disk space?
A: Generally, having less than 10-15% free space can lead to performance issues.

Q3: Why does my used space seem too high?
A: System files, caches, and Time Machine backups may consume space not visible in normal views.

Q4: How often should I check disk space?
A: Monthly checks are sufficient for most users, more frequently if you work with large files.

Q5: What's the best way to free up space?
A: Remove unused applications, clear caches, empty trash, and store large files in cloud or external drives.
