How long will Microsoft wait till the fix MAXPATH and other limitations? (and various other Win32 limitations that are usually a legacy porting helper thing from Win16). There would have been a good point with the introduction of Win64API - but Microsoft forgot about it and was apparently busy with something else.

I doubt it's too high up on the list of priorities. It would require really careful work to work in a backwards compatible way (there are almost certainly a tonne of apps that expect <=260 character filenames).

I guess the main thing is that it's one of those 'who cares' problems. The only time I've ever seen this limitation being complained about, it's by people who've had problems with npm.

That directory structure is undoubtedly horrible and is not mirrored by any other piece of software that I've seen.

Meanwhile it's also a "who cares?" problem for the npm people. They don't use this OS, and don't expect ever to do so.

I think the node_modules directory structure is a novel, though straightforward, solution to the problem of interdependent module versioning. It's very Unix; it reminds me a bit of GNU stow. It makes perfect sense that it will be tweaked in the new npm to be less redundant, but it only really makes sense to tweak systems that already work perfectly. (Otherwise they should be fixed first, then tweaked.) Certainly it's better than having a separate LD_LIBRARY_PATH setting for every command invocation! (even that doesn't fix everything...)

It doesn't even seem like an obvious solution to the problem. Take Maven for instance: a global dependency repository under which the dependencies are stored in the form <groupId>/<artifactId>/<version>. If X depends on Y.1 and Z depends on Y.2, so what? You have all the dependencies stored on your filesystem in a relatively flat structure.

If I had coded in Java on Windows for years, I wouldn't trust my sense of what's "obvious". I'm not too impressed by a "global" repository either. Python struggled against that stupid architecture for years before they got virtualenv in good working order. Node just took a shortcut to the future.

"All direct dependencies are in the node_modules directory, full-stop" is a pretty simple rule. Really, that's the only rule, and that's all of it. You don't need to worry about second-order dependencies, because those are direct dependencies of some other module, which means... they are in that module's node_modules directory.

I had the problems with a Java codebase in SVN (back when your user profile was still under C:\Dokumente und Einstellungen\Username\...

Apart from that there is a backwards-compatible way of using longer paths, which is prefixing with \\?\. Since MAX_PATH is a hard-coded constant there can only be an opt-in way of dealing with the problem. Sadly many application or framework developers these days still don't opt in.

It also creates the problem that if Application A can create such paths and Application B cannot read them, you'll be annoyed too. And Application A might just disable long path support to mitigate the problem, leaving the whole state as it is.

Recently that is where you'll have heard about it a lot, but people have been hitting the problem for years. I've hit it in a couple of distinct contexts in my time.

You hardly hear about it generally because people moan a bit then work around it so the problem goes away until next time, and sometimes people don't even moan about it because it is such an old problem they just think "oh, that again, better make my directory/file names and/or paths a bit shorter" and get on with their day.

The difference between this and with npm over recent times (causing the greater noise around the issue) is that twofold:

* linux/similar people hitting the problem in the wild for the first time (they've probably heard about it, but never had to deal with it) because their code is getting used on Windows which was much more a rare occurrence for them in the past, and being incredulous that such a problem exists in this decade

* Windows people wanting to use node and similar cool new tech on their preferred and/or mandated platform but hitting issues due to this problem in their environment (and in some cases being incredulous that someone wouldn't consider the implications of the limitation it in their design)

If you work on the sysadmin side of things, this comes up almost every time with directories on network shares. Explorer, cmd and PowerShell can't handle them and you need to resort to using robocopy or 3rd party tools like FastCopy. To delete stuff you often have to resort to hacks like robocopy mirroring an empty directory into the path before deleting it.
