FastCopyFastCopy download guide
Where to get FastCopy safely — official links only, with verification steps. This site never hosts installers.
11. Go to the official site only
The only official download source is fastcopy.jp. Third-party "download portals" bundle installers or lag behind on security updates. The button below links directly to the official site.
22. Pick installer or zip, 64-bit
The installer (fastcopy5.x.x_installer.exe) sets up Explorer integration; the zip is portable and keeps settings next to the executable. Modern PCs: choose the x64 build.
33. Verify before running
Check the published file size on the official page against what you downloaded, and verify the SHA/MD5 hash if the official page lists one. Any mismatch means do not run the file.
44. Install and first run
During install, optionally enable the right-click shell extension for "Copy/Paste to FastCopy". First launch: set your language in Option → if needed, and review the default Diff (Size/Date) mode.
Before you click "download" anywhere else
FastCopy is free — any site asking you to install extra "download managers" or pay for the standard edition is not the official source. The Pro edition with commercial licensing is sold only through the official channel.
