一款适用于NTFS文件系统的硬链接文件查重工具，在不改变文件夹结构的情况下节省大量磁盘空间。

A hard link file deduplication tool for NTFS file systems, saving a significant amount of disk space without altering the folder structure.

• 扫盘/读取文件夹：使用NTFS $MFT 原始数据直接解析，速度极快， 在一块满的20TB机械硬盘中，15s即可扫完。

  • 同时兼容普通扫盘和MFT两种模式，MFT需要管理员模式重启。

  • 自动过滤系统文件如$RECYCLE.BIN以避免出现意外错误。

• 校验和硬链接创建：使用SHA-256完整校验，并以至多1024文件一组创建硬链接。

  • 支持自动保护系统文件（如desktop.ini），自动跳过空文件。

  • 自动修复只读的文件和隐藏的文件。

• HashList保存和搜索

  • 支持以较高性能的搜索显示和列表排序，实测2 000 000项目全部加载显示仅需2s，且后续无卡顿。

  • 支持基本AND、OR搜索、完整路径搜索、HASH搜索

  • 支持自动读取已有列表并追加新文件

• Disk Scan/Folder Read: Directly parses raw data using NTFS $MFT, extremely fast. On a full 20TB hard drive, it only takes 15 seconds to scan.

  • Compatible with both regular disk scan and MFT modes. MFT requires administrator mode restart.

  • Automatically filters system files such as $RECYCLE.BIN to avoid unexpected errors.

• Verification and Hard Link Creation: Uses full SHA-256 verification and creates hard links in groups of up to 1024 files.

  • Supports automatic protection of system files (such as desktop.ini) and automatically skips empty files.

  • Automatically repairs read-only and hidden files.

• HashList Saving and Search

  • Supports high-performance search display and list sorting. In actual testing, loading and displaying all 2,000,000 items took only 2 seconds, with no subsequent lag. *

  • Supports basic AND, OR, full path, and HASH searches.

  • Supports automatically reading existing lists and appending new files.

• 仅支持NTFS文件系统，其他文件系统尝试启动会输出错误。

• HashList的二次加载：目前不支持校验文件是否一致，故用户需要自行确保前后两次运行的根目录一致，且文件未被修改！

• 建议配合diskpart的readonly属性设置使用，在处理完毕后进行只读锁，避免文件被改导致HASH失效！

• Only supports NTFS file systems. Attempting to start on other file systems will result in an error.

• Secondary loading of HashList: Currently, file consistency verification is not supported. Therefore, users need to ensure that the root directory is the same for both runs and that the files have not been modified!

• It is recommended to use this in conjunction with the diskpart's readonly property to apply a read-only lock after processing, preventing file modification from invalidating the HASH!
