磁盘空间，
一眼看清。
Your disk usage,
at a glance.
NcduWin 是一款现代、轻量的 Windows 磁盘管理工具——空间分析、矩形树图、极速搜索、一键清理、位置迁移，全部收在一个干净的窗口里。 A modern, lightweight Windows disk manager — space analysis, treemaps, instant search, one-click cleanup and folder relocation, all in one clean window.
把一个磁盘工具该做的，都做好Everything a disk tool should do, done properly
没有多余的功能，也没有多余的步骤。扫描、查看、清理、迁移——每一步都为「放心按下删除键」而设计。No extra features, no extra steps. Scan, inspect, clean, relocate — every step designed so you can trust the delete button.
双重视图Dual Views
左侧 ncdu 风格文件列表，右侧交互式矩形树图，占用结构同时以「表」和「图」两种方式呈现。An ncdu-style file list on the left, an interactive treemap on the right — the same data as both table and picture.
极速扫描Fast Scanning
多线程扫描，NTFS 磁盘直读 MFT 索引表，比传统遍历快数倍；node_modules、.git 等重型目录可只计量、不深入。Multi-threaded, and reads the NTFS index table (MFT) directly on turbo mode — several times faster. Heavy folders like node_modules are measured without deep scanning.
智能排序Smart Sorting
点击任意列头，按名称、大小、占比、文件数或类型排序；面包屑导航可一键跳回任意父目录。Click any column to sort by name, size, percentage, file count or type. Breadcrumbs jump straight back to any parent folder.
一键清理One-Click Cleanup
检测临时文件、浏览器缓存、pip/npm 缓存与大文件，按五级安全分级分类，勾选即清，系统关键文件不会被误判为垃圾。Finds temp files, browser caches, pip/npm caches and large files, classified by a 5-level safety scale. System-critical files are never mistaken for junk.
重复文件查找Duplicate Finder
三级漏斗算法高效定位重复文件，支持按类型筛选，自动跳过系统文件，并智能保留最佳副本。A three-level funnel algorithm finds duplicates fast, with type filtering, safe skipping of system files, and smart selection of the best copy to keep.
极速文件搜索Instant Search
Everything 风格的文件名搜索，直接基于扫描结果，毫秒级定位，支持实时过滤与通配符。Everything-style filename search over the scan results — millisecond lookups with real-time filtering and wildcards.
安全删除Safe Delete
右键发送到回收站（可撤销）或永久删除；删除在后台执行并显示进度，不卡界面。Right-click to send to the Recycle Bin (undoable) or delete permanently. Deletes run in the background with a progress indicator.
系统优化System Optimization
一键开关 Windows 自动更新，修复网络故障，刷新 DNS 缓存，重置应用商店缓存。Toggle Windows automatic updates, repair network problems, flush DNS and reset the Store cache — one click each.
保存位置迁移Relocate Folders
把库文件夹与软件数据目录搬到其他磁盘，原位置保留目录联接，软件照常使用，C 盘空间即刻释放。Move library folders and app data to another disk. A junction stays behind, so software keeps working and your C: drive breathes again.
可还原的迁移流程Restorable Moves
复制、校验、建联接、删旧目录分步进行；搬移前先做检查，失败可一键还原，残留文件可一键清理，还能找出占用目录的进程。Copy, verify, link, then remove — step by step, with a pre-flight check, one-click restore on failure, leftover cleanup, and detection of the process locking a folder.
中英双语Bilingual UI
内置简体中文与英语，选一次语言，以后自动记住。Built-in Chinese and English. Pick a language once — it remembers.
清爽界面Clean UI
柔和配色、清晰视觉层次、深浅色模式与自定义主题色，一看就懂的原生 Windows 体验。Soft colors, clear hierarchy, dark/light modes and custom theme colors — a native Windows feel you can read at a glance.
※「安全分级」指清理与删除时的五级危险度标注（L1 安全 – L5 高危），等级越低越可以放心清理；上表方块为示意。The safety scale is the 5-level risk label (L1 safe – L5 critical) applied during cleanup and deletion. The squares above are illustrative.
