This is one case where I think Windows is appropriately designed for its target audience.
I don’t really see the benefit of allowing users to create files with the same name in the same directory, yeah, yeah I know that case sensitivity means that it isn’t same name, but imagine talking to a user, guiding them to open the file /tmp/doc/File and they open /tmp/doc/file instead
The reason, I suspect, is fundamentally because there’s no relationship between the uppercase and lowercase characters unless someone goes out of their way to create it. That requires that the filesystem contain knowledge of the alphabet, which might work if all you wanted was to handle ASCII in American English, but isn’t good for a system which needs to support the whole world.
In fact, the UNIX filesystem isn’t ASCII. It’s also not unicode. UNIX uses arbitrary byte strings, with special significance given to a very small number of bytes (just ‘/’ and ‘\0’, I think). That means people are free to label files in whatever way they like, and their terminals or other applications are free to render them in whatever way seems appropriate, without the filesystem having to understand unicode.
Adding case insensitivity would therefore actually be significant and unnecessary complexity to add to the filesystem drivers, and we’d probably take a big step backwards in support for other languages
Oh, I realize why it is, I just don’t see it as an advantage, the whole argument is just a technical one, not a usabillity one.
You’re basically arguing that a system shouldn’t support user friendly things because that would add significant burden to the programmer.
The quintessential linux philosophy. Well done! I mean, what is language? Why have named code variables? This is just a random array of bytes!
No, I’m arguing that the extra complexity is something to avoid because it creates new attack surfaces, new opportunities for bugs, and is very unlikely to accurately deal with all of the edge cases.
Especially when you consider that the behaviour we have was established way before there even was a unicode standard which could have been applied, and when the alternative you want isn’t unambiguously better than what it does now.
“What is language” is a far more insightful question than you clearly intended, because our collective best answer to that question right now is the unicode standard, and even that’s not perfect. Making the very core of the filesystem have to deal with that is a can of worms which a competent engineer wouldn’t open without very good reason, and at best I’m seeing a weak and subjective reason here.
because it creates new attack surfaces, new opportunities for bugs, and is very unlikely to accurately deal with all of the edge cases.
Unicode case folding has been a solved problem for a long time. The Unicode standard has rules for which characters should be considered identical, and many libraries exist to handle it (you wouldn’t ever code this yourself).
Well you’re just asking an economic question, are the costs worth the benefits?
I’d argue that linux will never be a good or user friendly operating system without case insensitive filenames.
That isn’t an opinion but could be verified through scientific study of how confused people act. You don’t even need computers, just ask someone to get the “something SomeTHing” from a labeled box in a cupboard. Presumably science would show that case insensitive naming of things is always less confusing when humans actually use the system.
The truth is that programmers enjoy writing code far more than reading code. And especially to open source developers “usability” is a dirty word. It’s not about the value of a thing, it’s about the beauty of how it is done.
pov: you encode filenames in utf-1, just happens to contain one of those bytes
Let’s say you have a software that generates randomly named files, having the ability to use both upper case and lower case means you can have more files with the same amount of characters, but that sounds horrible and it’s the only thing I can think of atm
Idiot user! ;)
In case it’s not obvious, I agree that I don’t see much of a point in case sensitivity in an OS outside of simply providing additional options for various uses, it absolutely would be confusing for end users having to interact with it in many ways.
This isn’t “Windows design”… this is just inherited stone age bullshit from the DOS days when the filesystem was FAT16 and all file names were uppercase 8.3.
NTFS is case sensitive in its underlying design, but was made case insensitive by default, yet case preserving, for reasons of backwards compatibility.
If Microsoft has to design something from scratch, without the need for backwards compatibility, they go for case sensitive themselves. For example: Azure Blob Storage has case sensitive file names.
If you rename a file only changing the casing it doesn’t update properly, you need to rename it to something else and back.
This is so userfriendly I have been stumped by it multiple times.On the other hand in using Linux I have had a number of problems with the casing of files: The number is 0
If you rename a file only changing the casing it doesn’t update properly, you need to rename it to something else and back. This is so userfriendly I have been stumped by it multiple times.
To my great surprise, this has been fixed. I don’t know when, but I tried it on my Windows 10 VM and it just worked. Only took them 20 years or so :)
case insensitive by default, yet case preserving
This isn’t just a Windows thing… It’s the same on MacOS by default.
macOS also does this by default, but you can change it (though you have to reformat the disk in question). This is generally fine for non-system disks if you REALLY need it for some reason, but afaik it is not recommended for the OS disk due to assumptions that macOS-targeted binaries make (similar to the windows regex version matching that caused problems for a while because it became the unofficial best way to check windows versions for app install compatibility). It’s doubly annoying on newer Apple systems because the integrated SSDs are WAY faster than pretty much anything else you can connect to it. But for the most part, I find it’s more of a nuisance to keep in mind than a real problem (I’ve been dealing with dev-issue MBPs since about 2012).
As in the windows case, this is also an appropriate choice for the average Apple user (though the fact that they’re fairly ubiquitous as dev machines in many places is annoying on several levels, despite the generally solid best-case performance and thermals I’ve observed).
Huh I had thought case-sensitive was default on APFS/HPFS and you had to choose insensitive specifically but I guess not
Just checked on my work box - if you go into Disk Utility and start the process to add a volume, the default selection is
APFS, and there’s an option in the dropdown for forAPFS (Case-sensitive)
thank god it’s not case sensitive holy shit. i don’t understand the kind of person who would see that as a positive.
Seriously.
It sounds like a fucking nightmare. Imagine working on something for days and it refuses to work cause you accidentally capitalized 1 file name and dont notice it?
That sounds like the kind of shit they’d do in tech hell.
We regularly have that problem at work. Works on your development PC on Windows. Push to pipeline, get cryptic error messages. Once we were two people trying to figure it out for half an hour.
Case-sensitive file names. Why.
That’s why you never ever write the filename manually. Always copy paste it!
surely Git warns about stuff like this when you clone it, right ?
It tells you there’s a name clash, and then it clones it anyway and you end up with the contents of
README.MDinREADME.mdas an unstaged change.sounds like actually a good solution … tho doesnt sound like it would work for more than 2 similarly-named files
I don’t think it’s intended as a “solution”, it just lets the clobbering that is caused by the case insensitiveness happen.
So git just goes:
- checkout content of README.md to README.md (OS creates README.md)
- checkout content of README.MD to README.MD (OS overwrites README.md)
If you add a third or fourth file … it would just continue, and file gets checked out first gets the filename and whichever file gets checked out last, gets the content.
thats better than Git just choosing a file to keep.
Is it just me or is that more of a hinderance?
I absolutely fail to see the utility of having a user called Bob and bob, or a dir called Downloads and downloads. Capitalisation makes sense in code - at a glance I can know I’m looking at a Class or a var, but for system administration it has only ever wasted time, and not once made anything easier.
If capitalisation is used to indicate the start of words then it could make sense for a webserver to serve ExpertsExchange and ExpertSexChange. But yeah having 16 possible versions of “main” would be horrendous.
URLs aren’t case-sensitive though, so wouldn’t those necessarily have another kind of differentiator?
Definitely an inconvenient thing.
Yeah
I honestly don’t get why everyone is agreeing with Windows on this one. I just love how explicit Linux is.
file.txt is fucking file.txt. Don’t do any type extra magic. Do exactly as I’m saying. If I say “open file.txt”, it is “open file.txt”, not “open File.txt”.
The feature isn’t being able to create filenames with the same name, nobody does that. The feature is how explicit it is.
It would be so confusing to read some code trying to access FILE.TXT and then find the filesystem has file.txt
But why though? Do you really want a bunch of file.txt File.txt FILE.txt fIle.txt FiLe.txt FIle.txt flIe.txt… I once had a nasty bug the O in a file name was a 0 and I didn’t notice I can’t imagine the horrors this would cause.
Yeah I’ve definitely run into issues where case sensitivity causes problems. Especially in programs that are cross-functional between Windows and Linux. Like when I recently downloaded some bios files for a Playstation emulator and I spend time figuring out and troubleshooting why they weren’t working until it finally hit me the door McFly it’s cause the file name was in lowercase not uppercase. Than I cared to admit to figure out
Oooh, I’ve had that with some device. I think it was a camera or something like that. I’d forgotten about it. It took me ages to figure it out.
surely this is the only place where we would run into stupid syntax problems, right?
imo syntax bugs will be a thing until the end of time, they certainly beat having to rip out 90% of what you’ve done to fix it that’s for sure.
Yours is not too question why, yours is to admire the marvel of technology even if it’s worth than useless
It’s neat that Linux has the ability to do this, but I honestly can’t think of a good usecase for this. I think this is more confusing than it is useful
Git likes to have a word with you.
Command ‘Git’ not found
Beautiful
Huh, what makes this a use case in favor of case sensitive file names? How does git use this feature?
Create multiple branches that only differ in cases from a Unix OS so it breaks git for Windows users in the same project.
We had a repo with some really weird (filename) case issues on Mac also. I could only fix it on my home Linux machine, by deleting all the affected files, committing that, then restoring them with all lowercase names. Only time I’ve dealt with that in 20 years but it can happen!
I feel the same way about programming languages. There is no way that “User” and “user” should refer to different variables. How many times has that screwed people up, especially in a weekly typed language?
One of the many things that I feel modern versions of Pascal got right.
Nope. Completely different.
Case is often used to distinguish scope. Lowercase is local while uppercase is public. “Name = name” is a pretty standard convention, especially in constructors.
There is a ubiquitous use case in programming. There is not in the file system.
This is the first time I’ve seen uppercase denoting scope. Usually it is done with a “_” or “__” prefix.
Casing styles usually mean different identifier types.
snake_case or pascalCase for functions and variables, CamelCase for types, UPPER_SNAKE_CASE for constants, and so on.
If we want to apply this to file systems, you could argue something like: CamelCase for directories, snake_case for files, pascalCase for symlinks, UPPER_SNAKE_CASE for hidden files.
My point is not about how case is meant to be used my point is that it is very easy to make a mistake that is difficult to spot. I think it makes a lot more sense to the case insensitive, and force different names to be used.
My naming convention for C++ is that custom types are capitalized and instances aren’t. So I might write
User user;.
It’s quite useful for stuff like PROGRAM and Program in the same directory where PROGRAM is the program itself and Program is some unrelated files about the program. Bad example, but the case stands.
So what you’re telling me is that it’s useful when the software you use is made by absolute idiots?
It’s not about software. Program, PROGRAM were just placeholders for content. I know you can think more abstract and argue in better faith than this.
Replace ‘software’ by w/et placeholder thing
I think if you can write them in two different ways it should consider them two different things
Yeah I’ve been using Linux for a very long time. The amount of time I’ve spent on the case being incorrect is non-trivial. I’ve gotten better at not screwing it up throughout the years but the sum of advantages is far outweighed by the sum of debugging time spent.
Case sensitivity is so much of a problem, that in college, people were always told to keep all their filenames all lowercase, to avoid issues with them.
That’s the “getting better at not screwing up” part.
cd downloads
bash: cd: downloads: No such file or directory
cd Downloads
user@pcname:~/Downloads$
Bash has an option for that you can put in your
.bashrc:bind "set completion-ignore-case on"Zsh autocompletes lowercase input to the correct file or folder name when using tab. It’s great!
Fish does this too, it’s super convenient

I’m with windows on this one. Case insensitive is much more ergonomics with the only sacrifice represented by this meme. And a little bit of performance of course. But the ergonomics are worth it imo.
so cool story, on linux theres this thing called you can just not make case sensitive files, i do it a lot.
You can also just, use a case insensitive autocomplete setup as well. If you’re using a mouse idk why you’re even talking about this so that wouldn’t matter.
You can, but assholes out there won’t.
hence the inclusion of the case insensitive auto completion, it’s not 1982, you can use that now.
If I have two folders in my directory,
Dir1anddir2, what doesd <TAB>autocomplete to and what should it do?At least on zsh it would pop both of those as suggestions you can cycle through.
deleted by creator
In the case of zsh it will quite happily do either and ask you which you meant just like if they were called Dir1 and Dir2. Also works if you have a dir1 and Dir2 in the same directory as well
deleted by creator
it depends on your shell configs. In my case it sits at dir/Dir (case insensitive) waiting for me to specify 1 or 2, where as if you disable it, it’s dependent on whether or not you type d or D.
In fish it would immediately expand to dir2.
If you have “Dir1” and “DIR2” and you type “cd d”, your prompt will look like in the next picture. Fish automatically transforms “d” into “D”, because there is no dir starting with the lowercase “d”.
On a subsequent <TAB> you’ll get a list of dirs matching your prompt so far in which you choose an entry with the cursor key and enter it with the enter key.
When you say "canse insensitive file*, do you mean lowercase files? Or is there an option?
Idk why we talking about mouses. When I’m on Linux, most of the time it’s through ssh.
either or, whatever the fuck you want really.
You can just not use capital letters if you feel like it. Works pretty well. Or just use a case insensitive shell handler for pretending it’s not actually cased at all.
Hell im pretty sure you could just render all of the text in a certain case and call it a day lol.
I can make MY files all lowercase, but 99.999% of files on my computer are not created by me. And some of them have capital letters.
do you rent out your computer to other people? I think you’ll live tbh.
They are not created by people. They are created by programs.
what kind of programs are you using that use case in filenames. Smells like a skill issue to me.
Oh it’s even better, windows explorer can’t really do case sensitive
But NTFS is a case sensitive file system
This occasionally manifests in mind boggling problems
Yeah, it’s super weird. I once named a file with mixed case, but one of the letters was the wrong case. Renaming the file didn’t work at first. Renaming a file named PAscalCase.txt to PascalCase.txt resulted in no change to the filename. Windows continued to show it as PAscalCase.txt. I had to rename it to something totally different with different characters entirely, then rename it again to get it right.
Renaming it in Explorer does actually rename the file if all you change is the case (in current Windows, at least, see the pedantry below), but whatever mechanism Explorer uses to determine “has this file’s name changed” is apparently case insensitive. So it won’t refresh the file list. I imagine this is yet another one of those damn fool Windows 95 holdovers, or something.
You don’t have to do any multiple-renaming jiggery pokery. Just press F5 to refresh that Explorer window and magically then it’ll show you that the file’s name was indeed changed all along.
Nope. Tried that. Tried DIR in a command window too. But I never specified even what version of Windows I was running, so I’m a little unclear why you’re trying to troubleshoot a problem I was experiencing on windows nearly a decade ago. I guess this is what be mansplained too feels like.
NTFS is case insensitive because it’s supposed to be more POSIX compatible than its precursors.
You can enable case sensitivity in windows. It’s only disabled by default.
I wouldn’t do it though. It can only lead to problems, especially with poorly coded programs.
Same on MacOS - when you format a drive, you can pick whether it’s case sensitive or not.
The main problem with case-insensitive is that software sometimes is lazily developed: If a file is named “File.txt” and a program opens “file.txt”, then on a case-insensitive file system it will work fine. If you then format your drive to case-sensitive, the same software now fails to load the file. Source: tried case-sensitive filesystem on macOS some years ago.
Its given me issues installing the Fallout 2 Restoration patch.
Had this issue with Full Tilt! installer on Wine, fortunately the fix was easy
Vscode does not handle this well the one time I accidentally created 2 files with different cases. On one level it recognises them both as separate files, but other time thinks they’re the same.
The android build system used that limitation of Windows to prevent android from being built on Windows. They purposely had directories with the same name but different capitalization.
Why would they do that on purpose?
Maybe a reason why the Android Subsystem for Windows got canned?
Strictly speaking, this is a limitation of the default filesystem, and not the core operating system. If you mount a NFS share that is case sensitive, it will still be case sensitive.
Technically not a limit there either since you in windows on NTFS can set a flag on a folder to make it case sensitive
fsutil.exe file queryCaseSensitiveInfo <path>Can you apply this recursively to an entire drive? Say…
C:\You could, but should pick a different drive than c (this will likely break a ton of stuff)
Brb adding this to my set of pranks for windows users
The meme faces are backwards on this one.
This puts the win in Windows
