ACSync.CLI 1.0.0

ACSync — Incremental Update CLI Tool

A command-line tool for creating and applying incremental binary patches using 7z (LZMA2) compression.

Install

dotnet tool install --global ACSync

Usage

acsync <path> -l                  Create manifest
acsync <path> -u [-e ext1,ext2]   Apply patch
acsync <oldpath> <newpath> -m     Create patch

Create manifest -l

Scan directory and generate acsync_manifest.json (SHA256 hashes for all files).

acsync D:\app\v1.0 -l

Create patch -m

Compare old manifest with new directory, package delta as acsync_patch.7z.

acsync D:\app\v1.0 D:\app\v2.0 -m

If the new directory already has a manifest, it is loaded directly — no rescan needed.

Apply patch -u

Extract acsync_patch.7z into target directory. Supports:

• Auto-delete — removes files that no longer exist in the new version
• Exclude — skip specific file types (config files, etc.)
• Auto cleanup — patch file deleted on success

acsync D:\app\user -u
acsync D:\app\user -u -e .json,.ini,.yaml

Features

• SHA256 change detection — reliable, modification-time independent
• Multi-threaded scanning — fast for large directories
• LZMA2 compression — compact patches
• AOT compatible — low overhead, no heavy runtime dependencies
