Frequently Asked Questions

  • Can I distribute LongFiles myself?
    Yes, you can, provided that all documentation is provided with the release. If you are distributing LongFiles with a commercial package, then please let me know beforehand. There should also be a mention (somewhere) about http://www.tribbeck.com/ so that people can upgrade to the latest version.
  • Can I distribute/mirror this site?
    At this moment in time, I would say no - simply because I haven't decided if I like the new look and feel of this new site. When I've decided to settle the style down a bit, then I may take requests to mirror.
    By all means refer to the site by a link from your own site :-)
  • Does it work with Phoebe?
    At the time of writing, Phoebe has not been released, and so it is not known if LongFiles works on Phoebe. I cannot see a reason why it will not work.
  • Will I need it with Phoebe?
    If you intend just to distribute long filenamed files between other Phoebe machines, or those that have been modified with the new FileCore filing system then no, not really.
    However, if you wish to send long filenamed files to other machines, then you will. LongFiles will hopefully be extended to recognise the ADFS disc structure, and if it is a Pre-Phoebe format, it will kick in; otherwise, it will allow ADFS to do its structuring.
    If you are recieving long filenamed files from users of LongFiles, then I will be producing a "Read-Only" version of LongFiles which will read the discs with the long filenames.
  • What happened to LongDirs and the rest?
    One of the LongFiles bugs (SP001) has shown that LongDirs [and the rest] may become unstable in its current state. I hope to fix it when I have time.
  • What about FileCore, Unix and LongFiles?
    Adam Gundy (adam@impala.demon.co.uk) has produced code for reading LongFiles (versions 1 and 2) directory files that is available for Unix. Email him for more details. Note that I cannot support this.
  • How do I create long-filed data suitable for creating a CDFS disk prior to burning the CD?
    This is quite technical - only do this if you know what you are doing!

    Brief history: In version 2.08, the command *SpecialLongFS was added to allow LongFiles to work with specially prepared CDFS disks, allowing more than 10 character (or 8+3) filenames. This was added because Acorn Arcade wished to recreate their web site on the Acorn User CD-ROM. This was extended in 2.09 so that CDFS automatically defaults to special filenames and characters that can be used under ISO9660 format disks.
    If you want to create a directory structure that can be burnt to a CD-ROM with standard Acorn (and also PC) software, you will need to create a directory structure that uses the same special filenames/character that CDFS uses under LongFiles. There are several ways to do this, but it depends on what filing systems you have available to you:

    1. If you have a filing system which you do not use LongFiles with that has enough disk space (such as RAM)
      You will need to have a 'source' directory tree on one filing system, and a 'destination' directory tree on another filing system which you do not use LongFiles with (such as the RAM drive).
      1. Create the source directory tree containing your files.
      2. *AddLongFS <destination filing system> (or use the front-end)
      3. *SpecialLongFS <destination filing system> LONG__FS / (you cannot use the front-end for this)
      4. Copy the source directory to the destination filing system
      5. *RemoveLongFS <destination filing system>
      6. Close the destination directory down, and re-open if necessary. You should see that all the filenames are in the new LongFiles format.
      In order to see it in operation, take a small directory tree (such as ChangeFSI, which is 420K):
      1. Create a 512K RAM disk.
      2. Copy !ChangeFSI as ThisIsChangeFSI somewhere else on your hard disk (which is using LongFiles, of course!)
      3. Press F12, and type *AddLongFS RAM
      4. Then type *SpecialLongFS RAM LONG__FS /
      5. Then press RETURN, which will bring you back to the desktop.
      6. Copy ThisIsChangeFSI to the RAM disk
      7. When finished, press F12, and type *RemoveLongFS RAM, and then press RETURN again afterwards
      8. Close the RAM disk down, and re-open it. You should see two files, one called LONG__FS, the other called ThisIs/000
      9. If you are burning this using a PC, you can copy this onto a DOS floppy (or a DOS formatted Zip disk) quite happily, or if you are using Acorn software, then you can use the RAM::RamDisk0.$ as the source of the CD burn
      The best solution in terms of size and useability is to use a Zip disk, or another removable media which has a separate filing system from the others. If you are using Argo's Zip driver, then you can do the above, except use IZipFS instead of RAM.
    2. If you only have one filing system (such as ADFS), or not much disk space
      This system is, on the face of it, much simpler than the previous one. However, it does suffer from the drawback that it is not as easy to maintain.
      Before you can begin, you will need to download the CDLFSTools archive (which is available as an ArcFS archive 24836 bytes or a SparkFS archive 25360 bytes). This contains two programs - !ToCDLFS and !FromCDLFS.
      1. Create the source directory tree on your hard disk (using standard LongFiles)
      2. Load !ToCDLFS, and drop the parent directory of the source directory onto ToCDLFS's icon. This will convert the LongFiles names into the CDFS special characters
      3. If you are burning using a PC, you can copy the new structure onto a DOS floppy, or a DOS formatted Zip disk; if you are using an Acorn, you should be able to use the Acorn software with the source directory that has just been modified
      Since this changes some of special filenames that are used by LongFiles on your hard disk, you will need to use !FromCDLFS in order to convert the directory tree back again.
    Hint: If you want to use "LONG__FS" and "/" as the special characters for your normal hard drives, there is nothing stopping you from doing this. You will need to run !ToCDLFS on the entirety of your hard disk(s), and then either add *SpecialLongFS ADFS LONG__FS / in your boot sequence (along with any other FS you use), or set the options, and then save the options in the front-end if you load it on boot-up. Note that if you want to burn your CD (or copy the data onto a DOS formatted disk), then you'll have to kill LongFiles from that FS before copying.
