PHP Composer Package Cache Folder (~/.composer/cache)

Bottom Line: It is 100% safe to clear the PHP Composer cache. Running composer clear-cache will NOT delete your composer.json, composer.lock, or installed vendor/ packages.

What is the Composer Cache Folder?

Located at ~/.composer/cache on Linux/macOS (and %LocalAppData%\Composer\files on Windows), this folder is created by Composer (the PHP dependency manager).

When you run composer install or composer update in Laravel, Symfony, or WordPress projects, Composer downloads compressed .zip package archives and git clones into this cache. Over years of PHP development, obsolete package archives hoard 5 GB to 20 GB+.

Can You Delete Composer Cache?

✅ Yes, it is completely safe to delete.

• No project code risk: Your application source code, vendor files, and package lockfiles remain untouched.
• Auto-downloaded: Running composer install in the future will simply re-fetch active package archives from Packagist.

How to Safely Clean Up Composer Cache

Method 1: Using the Composer CLI (Recommended)

Open your terminal and run:

composer clear-cache
# OR
composer cc

Method 2: Manual Directory Wipe

# macOS / Linux
rm -rf ~/.composer/cache

# Windows (PowerShell)
Remove-Item -Recurse -Force $env:LocalAppData\Composer\files
