    Is there a program you use to create HDF image files on morphos?
    They tell me that it is present in the basic installation but I cannot find it!
    maybe it's downloadable on aminet?

    There is the FileWrite command in the standard MorphOS installation. It can write empty files like ADFs or HDFs, but unfortunately it first creates the file in RAM, so it's limited to your free RAM how big files you can write.

    I've made a request to MorphOS team that they'd change this to write files directly to HD without buffering it to RAM, so let's see... :)

    Basically creating these images is just writing null bytes into a file, so it wouldn't be any rocket science to write a separate program that'd do this.

    Or maybe you could create smaller files, but join them with the Join command as many times as you need... maybe a small shell script for this.. hmm...

    Well.. I created a shell script that will join bigger chunks into really big file and it worked... but it's quite slow and abusive regarding hd writes, so let's ditch that :)

    But I wrote a short Lua script to create empty files, read the comment section how to use it (notice that you give size in MiB): create_file.lua

    Haven't tested it too much, and no idea if the Lua implementation supports large (>2GB) files. Please let me know if somebody tries it. But at least this works out-of-the-box on a default MorphOS installation.

    If you have the SDK
    Code:
    dd if=zero: of=foo.hfd bs=1024 count=10k

    Well.. as said, FileWrite comes with MorphOS and you can use it to write a HDF. Type this in the shell:
    Code:
    filewrite test.hdf 209715200

    That creates a 200MB hardfile, now you can give it to an emulator and prepare it there, or mount it under MorphOS with FileImageCtrl and then format it with MorphOS's format option.

    If you want to create bigger HDF files that you don't have enough memory in your system, just use the Lua script I made and launch it in the shell like this:
    Code:
    LuaX create_file.lua Work:test.hdf 1024

    That would create a 1GB hardfile, and then do the rest the same way as told with the FileWrite image...

    Or use the MorphOS Software Development Kit's dd command as suggested by Polluks, which does the same as FileWrite or create_file.lua.

    You should be able to simply use the RawDisk: device to create and write file images.

    Those images can be mounted with mounter.

    So I have solved morphos unfortunately does not support 8 gig image files so the problem does not arise
    If I want to prepare an 8 gig image file and beyond I have to use Windows and WinUAE unfortunately
    That I like it or not

    This implies he has a physical volume he wants to create an image file of. As far as I can see, there's been no indication in this thread that this is what he seeks to achieve.

    Was the used filesystem something that should support that large files?

    I had to create an 8 gig image for my cd32 with terrible fire
    i know that cd32 has the limit of 8 giga maximum so i wanted to create n full image file of 3.2 and whdload and make an emergency backup without going through hundreds of whdload folders every time

    You could use the Ice File System to create an 8 gig file,

    In fact I had noticed while reading the file systems supported by morphos
    I could use an external hard drive with ice file system to create the image file
    I could create a 15/20 gig ice filesystem partition just to do this

    I guess exFat counts as proper file system and is fully supported. AFAIR NTFS was supported, too.
