Find duplicate files and link them using hard links to save a lot of disk space without deleting!

Duplicate Files Search & Link 是一款专为查找和管理重复文件设计的高效工具。它旨在帮助用户快速识别、分析和处理硬盘或网络驱动器中的重复文件，从而释放存储空间并优化文件组织。软件提供了直观的操作界面和强大的搜索算法，确保用户能够轻松找到并处理冗余文件，同时支持多种操作方式，如删除、移动、复制和创建符号链接，以满足不同需求。无论是个人用户还是企业管理员，都可以通过这款工具显著提升文件管理和存储效率。

Duplicate Files Search & Link (Duplicate Searcher) is an application for searching duplicate files (clones) and NTFS hard links as well symbolic links to the same file. It searches duplicate file contents regardless of file name (byte-by-byte comparison is used). This application allows not only to delete duplicate files or to move them to another location, but to replace duplicates with NTFS hard links or symbolic links as well (unique!).

This application was developed because I haven’t find any similar application which allows to operate NTFS-links.

A NTFS hard link is the file system representation of a file by which more than one path can refer a single file in the same partition. NTFS hard links allow several files to share the same space on the disk (the same file). For example, several applications can use NTFS-links to the same version of the library instead using different copies of the library files. If several hard links point to the one file, deleting of any hard links doesn’t cause deleting of the file and freeing disk space until the last hard link to the file will be deleted.

Features:

• Free for non-commercial use.
  Donations to support a further development are welcome! 😉
• Fast search engine can scan multiple independent drives at once or multiple files on the same SSD.
• Identify directory entries that already share a single linked file (hard or symbolic link) on Windows NTFS partitions.
  *Starting from version 6 also supports hard or symbolic links on Linux EXT2, EXT3, EXT4 partitions (tested only with EXT-partitions mounted with Ext2Fsd-driver for Windows).
• Identify audio, video and JPG files that contain identical media content but have different metadata information. (Unique and new in version 7!)
• Replace files with hard or symbolic links. (unique!)
  Replacing files with hard link means to link multiple directory entries (file names) to a single file on the same logical drive (aka volume/partition).
  Warning! Be very careful by linking system files, back-up files and files which can be altered by the user or OS. Hard or symbolic links aren’t independent files anymore, all the links point to single file and, if the file is being overwritten using any of link, all other links will also point to the new content.
• Detailed visualisation of duplicate files, NTFS hard links, symbolic links and junction points.
• Filter and sort files in many ways, including by fragmentation and hard links count.
• Supports long paths (path longer than 260 characters). Many other applications don’t support long paths.

OS: Windows XP / Server 2003 / Vista / Server 2008 (only versions up to 5.2.*),

00 科普 和 介绍

1. 什么是硬链接？

NTFS硬链接就像是给同一个文件起了多个不同的”名字”，这些名字都指向硬盘上同一份实际数据，无论通过哪个名字修改，内容都会同步变化。
它跟复制文件完全不同——复制会占用两份空间，而硬链接无论创建多少个，都只占用原文件的那一份磁盘空间。
只有当最后一个”名字”被删除后，文件才真正从硬盘消失，就像一把钥匙配多把锁，必须所有锁都拆了，门才能彻底打开。  

2. 这个程序干什么用的？

用来文件查重，并且一键删除多余的数据（不是删除你的文件！），可以让我们在不删除文件的情况下，挤出这些重复文件所占的多余空间！

并且在介绍里我也说了，这个程序可用于文件备份清理、硬盘屯屯鼠、以及一些拥有大量存储空间，但是重复文件过多的人群！

3. 这个程序和市面上那些已有程序有什么优势

优势可大了！
①我这个程序开源！并且是较为宽松的MIT协议！
②我这个程序可以用列表的形式直观呈现是否硬链接，是否可以创建，还会自动统计一次清除能节省多少空间！
③程序和代码及其小巧！程序本身只有130KB！还不够你一张自拍照大！
④性能极其优越！本程序采用C/C++编写、GUI程序功能使用的是完全的Windows原生api（连SHA256都是！）。使用的GDI+库，让你在高分辨率2K屏、4K屏下都能自适应缩放，完全不会像老程序一样模糊

4. 怎么看出程序有用的？

使用程序扫描清理完后，从文件属性看，空间占用似乎不变。可是！请你看看盘符界面，硬盘的空余空间却变大了！这就是有用，这就是真实的空余空间，不是虚假的！

01✨ 核心功能

• 重复文件分析：使用 SHA-256 哈希算法，对文件内容进行精确比对，精准找出深层目录结构中的重复文件。（文件夹下所有内容！）
• 一键批量硬链接转换：一键将所有重复文件转换为硬链接。程序会自动保留每组的第一个文件作为源文件数据，并“永久释放”其余物理文件以释放空间，同时在界面上直观展示总计可省空间。【释放文件数据并不会导致其他地方的文件被删除，而是所有相同文件都会指向同一个数据！这样会节省大量空间，可在硬盘剩余空间展示出效果！】
• 丰富的类型过滤器：下拉菜单内置了多种常用文件过滤规则，包括：常用视频、高清/蓝光视频、音频、图片素材、执行文件、压缩包以及文档等，也支持自定义 *.* 扫描。我没想搞太多格式的筛选，暂时先添加这么多了
• 高分屏 (High DPI) 适配：底层通过调用 GDI+ 实现了原生的 SetProcessDPIAware 高分辨率显示支持，确保在现代高分屏显示器上界面清晰锐利。并且，这是原生的GUI绘制方案，不依赖第三方各种庞大的框架，把程序体积控制在150KB以内！
• AHK 自动化脚本集成：提供一键生成 AutoHotkey (AHK) 自动化快捷键脚本 (ElegantHardlink_Hotkey.ahk) 的功能，支持通过快捷键 (Ctrl+H) 快速在外部调用 cmd 执行 mklink 指令。（此部分还没达到真正的方便，似乎有bug，建议别用）
• 右键上下文菜单：支持在文件列表中右键快速复制文件名、完整路径、SHA256 值，以及在资源管理器中直接定位文件。

02🛠️ 开发相关信息

• 开发语言：C/C++
• 图形界面：原生 Win32 API 和 GDI+
• 查重算法：Windows CryptAPI (计算 SHA-256)
• 极佳的兼容性：宏定义 _WIN32_WINNT 0x0501，保持了对早期操作系统（如 Windows XP）的兼容支持，同时解决基础版 XP SDK 隐藏 SHA256 宏的问题。本项目的目的就在于给硬盘数据做极致的空间整理，不管你的电脑有多老！（到xp都行）

03🚀 快速上手and快速教程

1. 在顶部下拉框选择需要扫描的 磁盘 或手动输入 地址。
2. 选择需要查找的 文件类型 过滤器（也可以不选）。
3. 点击 分析文件(查重)，等待右侧列表显示出相同 SHA-256 的重复文件组。
4. 确认无误后，点击 一键创建硬链接 完成物理文件的释放与替换。

一键扫描检测：点击 “Analyze” 按钮，可快速扫描系统，能识别出预装臃肿应用，如 Microsoft Copilot、GetHelp 等，还可找出隐私风险项，如活动历史记录、位置追踪等，以及检测到影响系统性能的设置，如游戏 DVR、视觉特效等。扫描结果会以不同颜色标注，红色项表示需要立即修复的问题，灰色项为已优化的安全设置，绿色项是无需改动的正常配置。
系统优化修复：可隐藏任务栏搜索框和 Widgets，禁用开始菜单推荐内容和 Edge 浏览器同步广告。能关闭 Windows 遥测数据收集，包括诊断数据、应用使用记录等，还可禁用活动历史、位置追踪、剪贴板云同步，阻止系统自动发送用户反馈。此外，还可以关闭游戏 DVR、Xbox 后台服务等占用资源的功能，禁用电源节流和不必要的视觉特效，如透明毛玻璃，同时优化注册表项，提升文件系统响应速度。
系统垃圾清理：能够自动清理临时文件、系统更新缓存等系统垃圾文件，释放磁盘空间，提升系统运行速度。
操作可逆保护：点击 “Restore” 按钮，可秒速回滚所有设置。并且在注册表修改前会自动备份，对于不可逆操作，如永久删除预装应用，界面会明确标注，保障系统安全，避免因操作失误导致系统问题。

CrapFixer: Fixes Crappy Windows 10 and 11 Issues

CrapFixer is a utility designed specifically to address and resolve the various frustrating issues that can arise within Windows 10 and 11, effectively streamlining the user experience. As its name implies, it focuses on fixing the “crap” that often hinders performance and usability.

Familiar and User-Friendly UI

While it shares some similarities with CCleaner, particularly in its approach to system optimization and maintenance, the developer of CrapFixer acknowledges that the inspiration drawn from CCleaner serves as a foundation rather than a direct replication. This program aims to provide tailored solutions that enhance the smooth operation of the Windows operating system by eliminating unnecessary files, optimizing settings, and addressing common bottlenecks that can degrade performance over time.

CrapFixer features a user-friendly interface that harkens back to earlier versions of Windows, focusing on simplicity to enhance the user experience. This tool enables users to analyze and resolve system issues with minimal effort.

Lightweight, Secure and Powerful

CrapFixer is dedicated to enhancing the overall user experience while preserving its lightweight and secure design. The latest update introduces asynchronous processing, significantly improving performance by allowing multiple tasks to run simultaneously without slowing down the user interface. Additionally, the tool now features a comprehensive F1 help option for each tweak, providing users with instant access to guidance and support whenever needed, thereby making it even more user-friendly.

In a move to broaden its functionality, CrapFixer has also integrated support for external scripts. This feature enables users to extend the tool’s capabilities with custom scripts tailored to their specific needs, allowing for greater flexibility and personalization. To facilitate this, users can easily create a plugins folder adjacent to the executable file, where they can store and access these scripts. This enhancement not only empowers users to customize their experience but also encourages a community-driven approach, fostering collaboration and innovation within CrapFixer’s user base.

One might think that searching and deleting empty directories is a trivial thing, but once you have hundreds of them it get’s really exhausting. That’s the reason I made RED. It’s a small and simple tool that searches and deletes empty directories recursively below a given start folder. And before deleting anything it let’s you check all empty directories it found.

FEATURES

• Shows empty directories before deleting them
• Supports multiple delete modes (including Delete to recycle bin)
• Allows white and black listing of directories by using filter lists
• Can detect directories with empty files as empty

DOWNLOAD LATEST BETA VERSION (2.3-BETA.0)

Update – February 2021: Finally I had some time to work on RED again and there is a new release on the way.
Actually, it is already finished but it still needs some testing. So if you feel like it, you can already try it and optionally send me feedback.
Okay, cool! Show me the beta version.
