Universal Disk Cloner

As its name suggests, Universal Disk Cloner is a practical piece of software designed to offer you the most straightforward way of cloning or wiping disks and images.

Tiny yet powerful disk cloner at your disposal

The application does not require installation to do its job, and it comes with a uber-simplistic, fool-proof UI, but, before we jump right into the important details, please note that you have to provide the tool with full administrative rights.
For starters, with the help of this tiny tool, you can clone disk to disk, disk to file, or file to disk, as well as wipe entire physical disks. It is capable of cloning drives without taking keeping regard to files actively used by your computer's system.

Allows you to clone and wipe disks clean, as well as to compress and protect them

Other than that, it should work with practically any hard drive, USB flash disks, SD Cards, virtual disks (VHD), and with FAT32, NTFS, EXT2/3/4, ReiserFS, XFS, JFS disk and almost all types of file systems. There's no actual limit concerning disk size. However, you should know that the destination disk should, quite logically, should be at least the same size as the source, if not bigger.
There are a couple more interesting features, as well. For instance, the app allows you to protect your saved image files with the help of AES-256. We'll go even further by pointing out that the maximum password size is 512 characters but the thing to remember here is that there's no way of recovering a lost of forgotten password. You've been warned.

Versatile, lightweight, and efficient tool for disk cloning

Even though it's marketed as a tool for advanced users, thanks to its straightforward approach, no-frills UI, and comprehensive documentation section, we think that with a bit of patience to read the section above, even the most novice of users can use the tool without significant problems.
Taking everything into account, Universal Disk Cloner is one of those apps that can easily act as the embodiment of efficiency in their respective field. That said, if you're looking for one of the simplest (if not the simplest) ways to copy the content of your old disks to newer ones, then we definitely recommend trying out Universal Disk Cloner.
