Etcher is the popular name used to refer to BalenaEtcher. BalenaEtcher is software whose source code is accessible freely and gives room for further modification and reallocation. Etcher is used for writing image files such as .img, .iso, and zipped folders creating USB flash drives that are bootable.

Before its existence, users experienced a hassle in writing images on detachable devices such as SD cards. Etcher can quickly burn an operating system into an SD card, for instance, thus getting rid of long and baffling procedures.
