== Files, Filenames, Fileheaders and more ==
Filenames can use all 256 different characters, and you can use User-user numbers from 0 to 254, (except for &E5 (this , which marks a deleted file). If Different to Amsdos, a file that is erased under FutureOS, this file is will not only be shifted to User user &E5, being completely purged but it will be physically removed from the directory. If a bunch of files is deleted the improvement becomes obvious. FutureOS renames and erases files video oriented, it’s very comfortable and fast, because the buffered directory is only written once to disc (? - meaning not clear).Furthermore one Files can show files be viewed on-screen (scroll up and down), print files, print directories, rename files (user and name)or printed. You can type a file and you can show also view the file-header. When typing a text-file one can define it is possible to set the number of columns and lines of a the window in which the text should be presented (overscan can be used)is displayed in. When looking at fileFile-headers you can look at the file-header of a normal are displayed as AmsDOS file or the icon-like file-header of a FutureOS program can be displayed. An AmsDOS file-header has 128 bytes, but only few of which some bytes are used (loading-address, file-length, start-address…)unused. Under FutureOS this 128 byte file-header is expanded, and every byte is used. The FutureOS file-header has two advantages: A file has now makes use of those unused bytes so that files have a 24 Bit length and can have a physical RAM select. Therefore a file can be defined to be loaded everywhere in the external RAM. Another feature is the fact that Also a FutureOS file-header can contain a graphic-graphical icon, a text-textual icon or a short description of the file. But FutureOS can still work with old AmsDOS file-headers.
