what is bettercopy fr?

BetterCopy is a free, open-source Windows utility that replaces the built-in file copy and delete operations with a faster, smarter engine. It is written in Rust and designed for modern computers with solid-state storage like NVMe drives and SSDs. When you copy files on a spinning mechanical hard drive, it detects the limitation and falls back to a slower, safer mode to avoid damaging performance. The tool works through keyboard shortcuts. You press Ctrl+Shift+V to paste and Ctrl+Shift+Delete to remove files. These shortcuts only activate when you are focused on Windows Explorer or the Desktop, so they do not interfere with typing or using other programs. A small background program watches for these key combinations and figures out where your cursor is pointing in the current folder. Where the built-in Windows copy handles files one at a time, BetterCopy splits the work across many threads. It uses two separate queues: one for small files under one megabyte and another for larger files. This design stops a single large file from blocking a batch of small ones. The program also detects whether a USB drive uses a modern or legacy connection protocol and adjusts its approach accordingly. The project focuses on staying lightweight and unobtrusive. It requires no administrator privileges, injects no code into the Windows shell, and leaves no background services or registry entries behind. When idle, it uses almost no CPU. A temporary progress window appears during operations and dismisses itself when the task finishes. In the project's own benchmark, copying 100,000 small files totaled around 800 megabytes. BetterCopy completed this in about 20 seconds, compared to 33 seconds for a tuned robocopy command and 4 to 5 minutes for Windows Explorer. The benchmark was run on a single test machine, so real-world results will vary. The project does not aim to compete with advanced tools like TeraCopy, but instead targets the typical user who wants faster copies without configuration.
