Etcher (whose official name is balenaEtcher) is a tool with which we can centralize the entire process of recording disk images on external USB or SD drives in one place. This utility will take care of processing the image, formatting the external drive and recording it with the correct format so that it is self-booting on the device for which it was designed.
This software is specially designed to be used by users with little computer knowledge. In addition to having an extremely simple and intuitive interface, it is responsible for preventing us from making any mistakes in the process. Without going any further, the tool hides the local mass storage units to avoid that we confuse them with the disk that we have connected. Small details that will make life easier for someone inexperienced.
Etcher supports ISO, IMG, ZIP, DMG, DSK, RAW, XZ, BZ2, HDDIMG, GZ, and ETCH formats, and the possibilities are enormous. We can record Linux distributions for installation from a pendrive, or insert a special operating system into SD cards to be detected by a Raspberry Pi. We can even use it directly to create a Windows recovery and installation drive from an ISO. The real incentive? That anyone can do it.
balenaEtcher is also a completely free and open source program, so it does not include any type of advertising that may hinder the experience.
