What Is Rufus?

Rufus, short for The Reliable USB Formatting Utility, with Source, is the software developed by Pete Batard. It is a free and portable application that doesn’t require installation. To better understand this utility, let’s see its features:

  • Rufus enables users to create a bootable USB flash drive using an ISO file. It supports various bootable ISO files, including some Linux distributions and Windows installation ISO files, and raw disk image files.
  • Users can use Rufus to download an ISO image of Windows 10 or 8.1 to their computer. And they can configure the release, edition, language, and architecture type according to their needs.
  • It also allows users to create a full DOS-compatible environment to run legacy tools with FreeDOS and the MBR partition Scheme.
  • It provides advanced boot selection, including Syslinux 4.07, Syslinux 6.04, ReactOS, Grub 2.04, Grub4DOS 0.4.6a, and UEFI:NTFS.
  • It supports two partition schemes (MBR and GPT) for users who want to create a bootable media with ISO image.
  • Rufus allows users to format their USB flash drives to FAT, NTFS, FAT32, exFAT, UDF, and ReFS file systems, set the cluster size, and edit the volume label.

In a word, this software is an ISO burner that is mostly used to format and create bootable USB flash drives or Live USBs with an ISO file easily.
