Folders with ..

[Meaxis]

I am running Node v10.15.3, on Windows 10 2004 (19041.338).
Node is able to create directories with two dots in them, directories that should not exist according to Windows as they are non-deletable and that gets mixed up with a directory of the same name.

To reproduce it, try creating a directory. I'm not sure if it's from the module I'm using or Node itself, but Node itself should prevent that.

@Meaxis, just out of curiosity, why did you decide not to use the issue template?

[Trott]

I would think Node.js should not prevent this as the operating system will prevent it. But you seem to be saying that the operating system allows it, which seems extraordinary to me. Can you provide actual code that does this? Is it remotely possible that the file names being created are not .. but instead using some Unicode character that resembles .?

Windows (to my knowledge) does not allow the creation of files or directories whose names consist only of . characters.

I'm sorry to have asked about the issue template, but we have been trying to figure out how to best structure it for Windows users.

I am running Node v10.15.3, on Windows 10 2004 (19041.338).

Thanks for providing this.

Node is able to create directories with two dots in them […]

That's fine, so does explorer.exe.

[…] directories that should not exist according to Windows […]

I don't see why these should not exist since we are able to create them using explorer.exe (the Windows GUI).

[…] as they are non-deletable […]

Non-deletable how? Did you use the fs module?

For more information, please see Recursive Directory Removal in Node.js.

To reproduce it, try creating a directory.

How did you create this directory? From the Windows GUI (explorer.exe), PowerShell, or something else?

I'm not sure if it's from the module I'm using or Node itself, but Node itself should prevent that.

Can you please explain this a little bit more? Are you insinuating that they (directories with two dots in them) should be prevented from being created since they cannot be deleted?

I think we need more information in order to properly address this issue. Some sample code would have been great.

I was able to create a directory with one and two leading dots, but you're right, you can't have a folder name that consists of only dots. I don't think that is what this question is about though, but it may be worth researching a little further.

[Meaxis]

Apparently, you can create those folders. Two dots at the end will automatically get removed, and if you have a folder named "LoremIpsum" and you try to create another one called "LoremIpsum..", it'll conflict. However, I was able to create LoremIpsum.. (with an existing LoremIpsum) through Node.

var fs = require('fs');
var dir = 'myfolder..';

fs.mkdirSync(dir);

@Meaxis, just out of curiosity, why did you decide not to use the issue template?

Apologies, I don't write issue reports very much, and I thought I only had to provide my operating system, how to reproduce the bug and what is the bug. Should I correct it?

[DerekNonGeneric]

/to @Meaxis

Should I correct it?

I certainly would. If you do, please use the appropriate issue template (omit the YAML frontmatter) and be sure to include sample code that would allow us to reproduce the problem (the way you attempted to delete the directory is missing). Thanks in advance if you do end up following through.

See explanation here: #33829 (comment).

You can still remove the directory using fs.rmdirSync(dir).

Closing as non-actionable.

Is this information in the documentation? If not, should it be?
