Overview

A file system management system that organizes, queries, and maintains downloaded browser binaries in a structured cache directory.

Description

Browser Cache Management provides a structured approach to managing downloaded browser binaries on disk. The cache:

Maintains a consistent directory hierarchy: rootDir/browser-platform-buildId/
Provides methods to list all installed browsers
Resolves executable paths from browser metadata
Supports uninstallation (removal) of specific browser versions
Handles platform-specific executable path resolution

Usage

Use cache management to list installed browsers, clean up old versions, or programmatically locate browser executables for launching.

Theoretical Basis

# Cache directory structure
rootDir/
  chrome-linux-131.0.6778.33/
    chrome-linux64/
      chrome          ← executable
  firefox-mac_arm-134.0/
    Firefox.app/
      Contents/MacOS/
        firefox       ← executable
