Destination over 260 characters fails

[JBBianchi]

Where trying to write a file with a path longer than 260 character, an error is thrown (the path has been changed but the length is the saame):

15:53:16.000 ERROR: Error processing queue: Could not find a part of the path 'C:\Dev\SomeInnerPath\Github\Project\src\innerpath\another-subpath\A.Very.Long.Project.Name.Like.Dotnet.People.Like\packages\some-random-scope\some-package-name\src\lib\events\a-very-very-very-very-very-very-very-very-very-very-very-very-very-very-long-file-name.ts'.

Even though LongPathsEnabledis true in the registry:

Or via gpedit:

One thing I find odd is that it's not the System.IO.PathTooLongException that seems to be thrown but it's definitely related to the 260 char limitation.

I read things about the Switch.System.IO.UseLegacyPathHandling, Switch.System.IO.BlockLongPaths or <longPathAware xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">true</longPathAware> in the application manifest but I don't think I have access to those or if they even apply to a VS extension...

Maybe WriteFile could rely on something else than System.IO, like ZetaLongPaths or other workarounds ?

Indeed let me take a look

Now I have this error straight away:

10:58:10.124 ERROR: Error processing queue: The filename, directory name, or volume label syntax is incorrect

I added small part which creates folder if it is missing - also it seems interop is not needed as System.IO is able to work with long paths when using that magic prefix - can you run test in solution "FileWriterTest" ? it should pass

[JBBianchi]

The test does indeed run successfully.

I changed the path in the test to the actual failing one and then the test fails. I think it's because I use .. in the path.

For instance, by replacing the path in test with

var path = @"C:\Dev\..\Dev\SomeInnerPath\Github\Project\src\innerpath\another-subpath\A.Very.Long.Project.Name.Like.Dotnet.People.Like\packages\some-random-scope\some-package-name\src\lib\events\a-very-very-very-very-very-very-very-very-very-very-very-very-very-very-long-file-name.ts";            

Which is basically the same, then the test fails.

I think it can be fixed by calling GetFullPath

var path = @"C:\Dev\..\Dev\SomeInnerPath\Github\Project\src\innerpath\another-subpath\A.Very.Long.Project.Name.Like.Dotnet.People.Like\packages\some-random-scope\some-package-name\src\lib\events\a-very-very-very-very-very-very-very-very-very-very-very-very-very-very-long-file-name.ts";
path = System.IO.Path.GetFullPath(path);

Then the test is successful.

ok thanks https://github.com/AdaskoTheBeAsT/Typewriter/releases/tag/v2.22.0

It seems to work flawlessly now. Thanks a lot for your reactivity !
