Rufus is a small, lightweight, and portable utility for Windows that helps you create bootable USB flash drives, USB-HDDs, memory cards, etc. It[SQ]s primarily used to :

*

Create bootable USB drives from ISO image files:

This is its main function. You can use it to create bootable USBs for installing operating systems (like Windows, Linux distributions, etc.), running diagnostic tools, or using other bootable utilities.

*

Format USB drives:

Rufus can format USB drives in various file systems (FAT32, NTFS, exFAT, etc.), which is useful before creating a bootable drive or just for general USB drive management.

*

Write an image to a drive:

Beyond ISO images, Rufus can also write other disk image formats.

*

Write DD images directly:

It allows for direct writing of DD images, useful for low-level disk operations.


Rufus is popular because it[SQ]s:

*

Free and open-source:

No cost to use and the source code is publicly available.
*

Portable:

Doesn[SQ]t require installation; you can run it directly from a USB drive or any other location.
*

Fast:

However, be cautious when using it: Formatting a drive will erase all data on it, so always back up important files before using Rufus to format a drive.
