File headers can also be viewed. FutureOS uses expanded but compatible file-headers, that allow a file to be up to 16 MB in length. The file-header can additionally specify the target RAM of a file. Further it can contain a file icon or a short file description.
Further there is the [[FutureOS Monitor]], which provides access to RAM, ROM, Z80 registes, I/O ports and allows the resting testing of routines.
