I built a Windows utility that copies 20,000 files in 7.7 seconds instead of File Explorer's 3 min 11 s

Hi everyone! I'm an independent developer, and over the last few months I have been working on Saetta , a small Windows utility that copies, moves and deletes files. I'm sharing it because I put a lot of work into it and I'd be glad if someone found it useful. Why I made it The idea came from copying folders with thousands of small files: File Explorer took minutes, and I got curious about why. It copies one file at a time , and with small files the time goes more into handling each sin

AI 分析

痛点：Windows 资源管理器逐个复制文件，处理海量小文件（几千到几万个）时耗时是优化引擎的数倍到数十倍，删除同样慢。

目标用户：频繁搬移大量小文件的 Windows 重度用户：开发者、运维、视频/素材工作者、NAS 与移动硬盘用户

证据：File Explorer took minutes, and I got curious about why. It copies one file at a time… 20,000 files of 64 KB, SSD to SSD: 7.7 s vs 3 min 11 s; Deleting 10,000 small files in 2,000 folders: 1.6 s vs 17.8 s

变现：免费版+付费 Pro：多任务队列、哈希校验、右键菜单与拖拽集成、计划任务、企业批量授权；一次性买断 15–25 美元或年订阅

MVP：用 C++/Rust 写只做「批量小文件复制/删除」的右键菜单工具，按目标盘类型（SSD/HDD/USB）自动切换并行或顺序写策略，仅支持本地 NTFS，内置与资源管理器的同机跑分对比页，2 周内出可测 beta

竞品：TeraCopy、FastCopy、Robocopy、SuperCopier、ExtremeCopy、Windows File Explorer

摘要：独立开发者用 C++ 自写复制引擎，2 万个 64KB 小文件 SSD 间复制 7.7 秒，资源管理器需 3 分 11 秒；删除 1 万个小文件 1.6 秒 vs 17.8 秒，并公开了全部测速数据。帖子是免费工具发布，未提及收费、用户付费意愿或收入。同类需求已被 TeraCopy、FastCopy 等成熟工具占据，竞争空间有限。
