CopyWin 4.75

CopyWin mirrors the Windows drive, including all files and programs, to a second disk, USB drive, or MicroSD card.

Features

Ultra-fast mirror updates, especially between SSDs.

Makes the target drive bootable.

You can interrupt the copy process at any time and resume it later without losing the progress already made.

Free, with anonymous download, no hidden actions for upload, download, or automatic updates.

Works without installation — just click and run (Click To Run).

Important considerations

Requires administrative privileges to operate.

The first mirroring operation to a USB flash drive may take a long time. It is recommended to let it run overnight.

USB 2.0 devices are slow. For better performance, prefer USB 3.0 or MicroSD cards, which tend to be faster — many PCs can boot normally from MicroSD.

After mirroring, the target drive will be identical to the Windows drive. All files not present in the source will be deleted from the target. It is recommended to use a target drive without important data or resize existing partitions via diskmgmt.msc to create dedicated space for mirroring.
