Decompress — Archive & Compression Reference
Quick-reference skill for decompression algorithms, archive formats, and extraction techniques.
When to Use
- Extracting tar, zip, 7z, rar, or other archive formats
- Choosing between compression algorithms (gzip, zstd, brotli, lz4)
- Handling corrupted or partial archives
- Streaming decompression for pipelines
- Understanding compression ratios and performance tradeoffs
