2. Decomress the image using your File Manager. If you don't have an archiver (on Windows for example) - the [7-Zip](https://www.7-zip.org) is a great choice.
2. The downloaded OS image is compressed. Balena Etcher can flash compressed images, but it consumes more RAM and this process slower than with uncompressed image. If possible, we recommend you to decompress the image (from `*img.bz2` to `*.img` file). You can do this using any archiver or your file manager.
