FastZIP

English | 简体中文 | 日本語 | 한국어 | Français | Deutsch | Español | Italiano | Português | Русский | العربية | Türkçe

A native Rust archive tool with GUI and CLI. Compress, extract, test, and benchmark — all in one binary with no external dependencies for common formats.

Features

• Compression & extraction — 12 output formats with 5 compression levels
• Archive testing — stream through entries and verify CRC32 integrity without extracting
• Performance benchmark — CLI benchmark suite measuring compression ratio and throughput across all formats and levels
• Self-extracting archives — wrap any archive into a standalone .exe (SFX)
• AMSI malware scanning — optional Windows Antimalware Scan Interface integration for extracted files
• Hash/checksum — SHA-256, BLAKE3, CRC32 for any file
• Split volumes — create and read multi-volume archives (.zip, .7z)
• Password protection — AES-encrypted ZIP and 7z archives
• Codepage handling — automatic encoding detection for non-UTF-8 filenames (Shift-JIS, GBK, etc.)
• Pipe support — read/write archives from stdin/stdout (-)
• Compression presets — save and reuse compression settings
• WIM / ISO read-only — list files inside WIM and ISO 9660 images
• Windows shell integration — right-click context menu for compress/extract
• Localization — 12 languages (English, Chinese, Japanese, Korean, French, German, Spanish, Italian, Portuguese, Russian, Arabic, Turkish)

CLI usage

The main binary includes both GUI and CLI. Use subcommands to access CLI functions.

Inspect archives

fastzip list archive.zip
fastzip list archive.rar --password secret
fastzip list - < archive.tar.gz --format tar.gz

Extract archives

fastzip extract archive.zip -o ./output
fastzip extract archive.7z --flat --password secret
fastzip extract archive.zip --scan          # AMSI scan extracted files
fastzip extract archive.zip --codepage 932  # Shift-JIS filenames

Compress files

fastzip compress ./folder -o output.zip
fastzip compress ./folder -o output.7z --level maximum
fastzip compress ./folder -o output.zip --sfx            # self-extracting
fastzip compress ./folder -o output.zip --volume 100M    # split volumes
fastzip compress ./folder -o output.7z --password secret --encrypt-file-names
fastzip compress ./folder -o output.tar.zst --threads 4

Test archive integrity

fastzip test archive.zip
fastzip test archive.7z --password secret

Hash / checksum

fastzip checksum file.dat --algo sha256
fastzip checksum file.dat --algo blake3
fastzip checksum file.dat --algo crc32

Benchmark

fastzip benchmark -o ./results

Other commands

fastzip formats              # list supported extensions
fastzip backends             # show backend availability

A slim CLI-only binary (fastzip-cli.exe) is also included for scripting — it skips GUI startup overhead entirely.

Performance benchmark

FastZIP includes a CLI benchmark that tests every format (ZIP, 7z, TarGz, TarBz2, TarXz, TarZst, TarLz4, Gz, Bz2, Xz, Zst, LZ4) across three compression levels (Fastest, Normal, Maximum) on both compressible and incompressible 1 MB data sets. Results include compression ratio and throughput in MB/s.

fastzip benchmark -o ./results

The benchmark produces a directory of compressed archives along with console output showing:

Metric	Description
Compression Ratio	output_size / input_size (lower is better)
Throughput (MB/s)	input data processed per second (higher is better)
Elapsed Time	wall-clock duration per format/level combination

Comparison with other tools

To compare FastZIP against 7-Zip and other installed tools, use the comparison scripts in tools/:

# Windows PowerShell
.\tools\zip_compare.ps1     # Compare ZIP compression performance
.\tools\zip_perf.ps1        # Detailed ZIP performance profiling

These scripts run identical workloads across multiple tools and report speed, ratio, and time differences.

Build from source

Requirements: Rust toolchain (edition 2024), Windows 10+.

git clone https://github.com/cccccyccccc/fastZIP.git
cd fastZIP
cargo build --release

The build produces three binaries in target/release/:

• fastzip.exe — main GUI + CLI
• fastzip-cli.exe — slim CLI only
• sfx-stub.exe — self-extracting archive stub
