Arch WSL Disk Cleanup

Guide systematic disk space cleanup on Arch Linux WSL systems. Follow a layered approach: start with safe cache cleanup, then review installed packages, then scan for large files and directories.

Pre-flight Checks

1. Confirm the environment is Arch Linux: head -3 /etc/os-release
2. Check if running in WSL: grep -qi microsoft /proc/version
3. Check current disk usage: df -h /
4. Identify available package managers: which pacman yay paru 2>/dev/null

Record baseline for the final report — save the output of df -h / and:

du -sh /var/cache/pacman/pkg/ ~/.cache/ 2>/dev/null
