FastCopyWhat is FastCopy? Features & system requirements
FastCopy is a free Windows file-copy and backup utility known as one of the fastest available. It skips the OS cache, parallelises reads and writes across separate threads, and supports long Unicode paths and UNIX-style filters. It runs on Windows 7/8/8.1/10/11 and Windows Server 2012 through 2025.
How it reaches device-level speed
- Different drives: reading and writing run in parallel threads (SSDs always use this mode).
- Same drive: the buffer is filled sequentially, then written sequentially, avoiding seek thrash.
- I/O bypasses the OS cache entirely, so other running programs are not slowed down.
- Asynchronous I/O pushes the device close to its raw limit.
Other built-in capabilities
- Copy (and delete) with full Unicode filenames and paths longer than the 260-character MAX_PATH limit.
- UNIX-wildcard include/exclude filters, with date- and size-based extended filters.
- Written in plain Win32 API (no MFC) — small footprint and fast startup.
Read this before your first copy
Depending on the operation mode, destination files can be overwritten without confirmation. Sync mode may delete files on the destination, and delete mode force-removes files and directories (read-only attributes are cleared first). Read the license disclaimer and the operation mode reference before running large jobs.
