      Linux still unable to catch up with NTFS when it comes to filename length, sadly. 256 bytes in an era of Unicode is ridiculous.

        NTFS also has a 255 limit, but it’s UTF16, so for unicode, you will get more out of it. High price to pay for UTF16. Windows basically is moving stuff between UTF16 and ASCII all the time. Most apps are ASCII but Windows is natively UTF16. All other modernly maintained OS do UTF8, which “won” unicode.

        The fact that all major Unix (not just Linux) filesystems are to 255 bytes says it’s not a feature in demand.

        I’d much rather have COW subvolume snapshotting and incremental backup of btrfs or zfs. Plus all the other things Linux has over Windows of course.

          I think this is a biased way of putting it. NTFS way is easy to understand and therefore manage. What’s more important is that ASCII basically means English only. I’ve seen enough of such “discrimination” (stuff breaks etc.) based on used language in software/technology and it should end for good.

          All other modernly maintained OS do UTF8, which “won” unicode.

          UTF8 is Unicode. UTF8 symbols can take more than 1 byte.

          Plus all the other things Linux has over Windows of course.

          There are also encryption methods that slash maximum length of each filename even further.

            Of course UTF8 is Unicode. The cool thing about UTF8 is that is ASCII, until it isn’t. It cover all of Unicode, but doesn’t need any bloat if you are just doing latin characters. Plus UTF8 will seamless go through ASCII code and things that understand it do, others just have patches of jibberish, but still work otherwise. It’s a way better approach. Better legacy handling and more efficient packing for latin languages. Which is why it “won” out. UTF16 pretty much only exists in Windows because it’s legacy it will be hard for it to escape.

            LUKS is by far the most common encryption setup on Linux. It’s done at block layer and the filesystem doesn’t know about it. No effect of filename length, or anything else.

              None of that helps or discards anything I’ve said above. But it allows to say that NTFS limit can be basically 1024 bytes. Just because you like what UTF-8 offers it doesn’t solve hurdles with Linux limits.

              LUKS is commonly used but not the only one.

                Linus’s VFS is where the 256 limit is hard. Some Linux filesystem, like RaiserFS, go way beyond it. If it was a big deal, it would be patched and widely spread. The magic of Linux, is you can try it yourself, run your own fork and submit patches.

                LUKS is the one to talk about as the others aren’t as good an approach in general. LUKS is the recommended approach.

                Edit: oh and NTFS is 512 bytes. UTF16 = 16bit = 2 bytes. 256*2 = 512

                  Well it should probably go further and offer more of another kind of magic - where stuff works as user expects it to work.

                  As for submitting patches, it sounds like you suggest people play around and touch core parts responsible for file system operations. Such an advice is not going to work for everyone. Open source software is not ideal. It can be ideal in theory, but that’s it.

                  LUKS is the one to talk about as the others aren’t as good an approach in general. LUKS is the recommended approach.

                  It looks like there are enough use cases where some people would not prefer LUKS.

                    I have lived quite happily, on pretty much only open source for over 12 years now. Professionally and at home (longer at home). Debian I put with Wikipedia as an example of what humans can be.

                    There is no gate keepers in who can do what where. Only on who will accept the patches. Projects fork for all kinds of reasons, though even Google failed to fork the Linux kernel. If there is some good patch to extend the filename limit, it will get in. Enough pressure and maybe the core team of that subsystem will do it.

                    Open source already won I’m affriad. Most of the internet, IoT to super computers, runs open source. Has been that way for a while. If you use Windows, fine, but it is just a consumer end node OS for muggels. 😉

                    If you setup a new install, and say you want encryption, LUKS is what you get.

          Linux file system is shit? Otherwise I don’t get why you’ve used the “because” word. NTFS is certainly not shit.
