  1. dosfs

    Hi ALL
    I'm using dosFsVolFormat to be able to use dosSetVolCaseSens (activated
    case sensitive with filenames), the problem is that it "Allows
    case-sensitive filenames of up to 40 characters", i'm using filenames
    upto 1024 on my HDD (iso 9660 + joliet + others).
    Is there anyway to increase filename length more then 40 characters ?

    BR.
    Tarek.

    40+ seems to work ok for me on an ATA compact flash formated for
    FAT16...

    The answer depends on which version of vxWorks, and on whether you
    configure VFAT handling.

    The 40-character file names are for the special vxWorks-specific
    "not quite DOS" file system, which also allows file sizes to exceed
    4 gigabytes. This format is not compatible with actual DOS file
    systems, however, and is being phased out in vxWorks 6.

    VFAT handles up to 255 characters in each file name, and in vxWorks
    6.x, can deal with Unicode (via UTF-8, rather than UTF-16/UCS-2).

    ISO9660 is a completely different format from all of these, used
    mainly for CD-ROM devices.
