软件特点
用内存安全的 Rust 编写
惊人的快 – 由于使用了或多或少的高级算法和多线程
免费，开源，无广告
多平台 – 适用于 Linux、Windows、macOS、FreeBSD 等
缓存支持 – 第二次和进一步的扫描应该比第一次快得多
CLI 前端 – 轻松实现自动化
GUI 前端 – 使用 GTK 4 框架，看起来类似于 FSlint
无间谍 – Czkawka 无法访问互联网，也不会收集任何用户信息或统计数据
多语言 – 支持多种语言，如波兰语、英语或意大利语
使用多种工具：
Duplicates – 根据文件名、大小或哈希查找重复项
空文件夹 – 借助高级算法查找空文件夹
大文件 – 在给定位置查找提供的最大文件数量
空文件 – 在驱动器中查找空文件
临时文件 – 查找临时文件
相似图像 – 查找不完全相同的图像（不同的分辨率、水印）
相似视频 – 寻找视觉上相似的视频
相同的音乐 – 搜索具有相同艺术家、专辑等的音乐。
无效的符号链接 – 显示指向不存在的文件/目录的符号链接
Broken Files – 查找无效或损坏的文件
错误扩展名 – 列出内容与其扩展名不匹配的文件
清理重复项和释放计算机上的存储空间是建议您定期执行的维护任务的一部分。虽然可以手动进行操作，但其他操作需要专门的工具来完成工作。 Czkawka 可能是您在需要删除 PC 上不必要的文件时寻找的解决方案。
更新日志
Version 12.0.0
Breaking changes
Users
Due to changes in the broken files mode, which now supports multiple checkers and includes additional checks, the file type is no longer stored in the cache. Existing cache files are incompatible with this version and will be automatically regenerated
The prehash method has been updated, so cached hash is no longer valid, so it will be automatically regenerated
Similar images cache files are incompatible with this version due to geometric invariance support and will be automatically regenerated
Similar videos cache files are incompatible with this version due to the switch to a new visual matching engine and will be automatically regenerated
The --crop-detect CLI option for similar videos now accepts true/false instead of none/letterbox/motion - the motion mode has been removed
Core
Switched AV1 encoding from the very slow libaom-av1 to libsvtav1 - #1888
Added a noise reduction option to Video Optimizer mode, which can significantly reduce file size for noisy videos - #1888
Added support for custom optimization commands in Video Optimizer mode - #1888
Added experimental hardware-accelerated video encoding - #1900
Broken files can now be checked using multiple checkers - #1900
Checking for broken videos has been split into fast (ffprobe - headers only) and slow (ffmpeg - full decoding) modes - #1900
Added the ability to stop checking for hardlinks along with progress tracking of this operation - #1900
Added the ability to exclude images/videos with the same resolution - #1900
Added the ability to find similar videos by comparing their audio - #1919
Empty files mode now allows detection of files containing only non-printable ASCII characters or null bytes (\0) - #1919
Temporary files mode now allows customization of searched file extensions - #1919
Prehash now also hashes the end of files to detect differences earlier - #1919
Added support for detecting corruption in Fonts (TTF, OTF, TTC), Markup (JSON, XML, TOML, YAML, SVG), and Archives (7z, gz/tgz, tar, zst, bz2, xz) - #1919
Added geometric invariance support for similar images mode, allowing mirrored, flipped, and rotated images to be matched - #1944
Fixed a bug where relative symlinks were resolved without considering the parent directory - #1900
Fixed a prehash cache bypass that caused full hash computation on some files during a second scan - #1907
Extended integration tests, to prevent regressions in the future - #1919
Fixed unstable prehash when the read syscall returned fewer bytes than requested - #1948
Switched visual video duplicate detection engine from vid_dup_finder_lib to similario_core, adding configurable window count, duration tolerance, and subclip detection - #1948
Fixed a bug where similar videos were not deleted when using reference-folder mode - #1948
Replaced nom-exif with little_exif for reading EXIF orientation data - #1948
Fixed reversed logic of hiding hardlinks in similar images/videos modes - #1952
Added a $TRASH excluded-items preset (alongside the existing DEFAULT) to exclude common Trash/Recycle Bin paths from scans - #1962
Reworked internal progress stage tracking, to unify progress calculations across all backends - #1962
GTK GUI
Fixed a crash when using the sort button - #1837
Krokiet
Added separate buttons for moving files to trash and permanently deleting them - #1900
Added a new custom selection popup - #1809
Added an image comparison tool to detect visual differences between similar images - #1888
Added a context menu (right-click) - #1888
File and folder selection dialogs no longer blocks the main thread - #1809
Fixed an issue where thumbnail generation settings were not respected in Similar Videos mode - #1809
Added notification support - #1837
The femtovg backend no longer produces blurry fonts - #1900
Changed default selection behavior from "select one item" to "select all except one item" - #1913
Added the ability to configure which selection buttons are visible in the UI - #1913
Added invert selection within groups - #1915
Fixed shortest/longest path selection modes, which previously compared only paths without file names - #1919
Ability to restore save/restore data in custom popup - #1919
Added "Rename on conflict" option to the move/copy popup to automatically rename files instead of skipping them - #1948
Added the ability to rename items - #1962
Cedinia
Initial experimental release of Cedinia, a new Android app with touch support - #1821
Prebuilt binaries
Linux prebuilt binaries now include AVIF support (requires libavif and libdav1d)
Windows ZIP package now includes Krokiet binaries and a README to simplify migration to the new frontend
Krokiet binaries for all backends are now packaged in ZIP files, with additional scripts to launch them with a selected backend
Mac Intel binaries are no longer provided due to very long build times on GitHub CI
Added installation scripts (misc/install_scripts/) for Linux (apt/dnf/pacman/zypper), macOS (Homebrew), and Windows (winget)
