Disk Auditor vs DiskLens
Both stand on disk space analyzers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Choose Disk Auditor if you want a free Windows tool for exploring disk usage, comparing directories, or checking duplicate files. Its portable executable avoids installation, and its exports support several common formats. Look elsewhere if you need a platform other than Windows or require a code-signed application.
