Better filesystem.

ADFS just seems to be too limited for today’s standards. i’ve been having many problems just using a usb stick because the limitation of 47/77 files per directory is pretty ridiculous. It seems it isn’t the only limitations. Max volume/file size is about 512MiB and 10 character filenames. It makes RiscOS compared to some other arm systems look like dos.

I don’t know where you’ve dug that system up from, but it is seriously ancient. Most of us run with no limitations on the number of files per directory, and maximum volume size of 256GiB.

One of my Filecore-formatted directories has 1628 files in it – I just checked.

no limitations on the number of files per directory

I think this is not correct, it depends on many things (like length of filenames of objects inside the dir), but there is a limit, it is just much much higher than previously. ISTR around 80000 dir entries.

and maximum volume size of 256GiB.

When using 512 bytes/sector format. On 4K native discs, the limit is therefore 2 TiB.

Anyway, there is a bounty for better FS, and here’s the thread: https://www.riscosopen.org/forum/forums/8/topics/612

Shall I tell you how much used to be in my Manga cache directory until I wrote some routines to tidy it?
[hint: your figure multiplied by three is in the right sector of the map]

The alarm bell ringing here is that Krzysztof is using a USB device, yet has somehow ended up with an old style map. The obvious question is to ask how that USB device was actually formatted. What is Krzysztof’s system, and how did he format the media?

Having a quick look at the source of HForm, it looks as if it might ask if you want BigDir.

If you say no, you’ll probably end up with the 77 files/dir, 10 char filenames format.

You’ll want to say yes to use the modern and improved format.

I’ve used a 64 gigabyte memory stick formatted as fat32 under windows so i could move files to my rpi running risc os. I had some archimedes games on it and when i tried to open the drive with more than 47 files it just said the drive is corrupted. I don’t really know stuff about the filesystem RiscOS uses. I posted the data from wikipedia which looked possibly true due to my case of “corrupted drive”

If it is FAT32, you need to install Jeff D’s FAT32FS addon from https://sites.google.com/site/jeffreyadoggett/

I believe that’s included as standard in RISC OS Direct.
