Exception: (2) The target file is a directory, not a file on DirectoryInfo.Delete(true)

[LinkForce]

Trying to delete a folder gives me the exception on the title. Using 2.2.6 version downloaded from nuget.

I could not reproduce using this test:

private void AlphaFS_DirectoryInfoTest(bool isNetwork)
  {
     using (var tempRoot = new TemporaryDirectory(isNetwork))
     {
        var folderSrc = tempRoot.CreateRecursiveTree(5);
        var dirInfo = new Alphaleonis.Win32.Filesystem.DirectoryInfo(folderSrc.FullName);
        
        Console.WriteLine("Input Directory Path: [{0}]", dirInfo.FullName);

        Assert.IsFalse(System.IO.File.Exists(dirInfo.FullName));

        Assert.IsTrue(System.IO.Directory.Exists(dirInfo.FullName));

        dirInfo.Delete(true);
        
        Assert.IsFalse(System.IO.Directory.Exists(dirInfo.FullName));
     }
  }

=== TEST LOCAL ===

Input Directory Path: [C:\Users\jjangli\AppData\Local\Temp\AlphaFS.TempRoot.ëkg15ëw2\Directory.f4s5sxbn]

=== TEST NETWORK ===

Input Directory Path: [\\DESKTOP-0A2DGD2\C$\Users\jjangli\AppData\Local\Temp\AlphaFS.TempRoot.üëïüwdvü\Directory.íttúdjyt]

The exception should also mention the path to the file, could you verify it is indeed a file?

[LinkForce]

Yes, it is definitely a Directory, and the directory is created by AlphaFS itself. My code is something like this:

var dir = new DirectoryInfo("C:\\Path\\to\\Directory");

if (dir.Exists)
    dir.Delete(true);

dir.Create();

//doing some work, creating subdirectories and files inside that folder and creating a zip 

Console.WriteLine("Deletando arquivos Físicos");
dir.Delete(true);

I rolled back my application to the AlphaFS version I was using before, 2.0.1, and the code now works again just fine.

I can't provide the actual code because it is proprietary code but any tests that you may want me to make and provide info I can gladly do for you.

[Yomodo]

Ok, could you try the following, to see if it makes any difference:

var dir = new DirectoryInfo("C:\\Path\\to\\Directory", Alphaleonis.Win32.Filesystem.PathFormat::FullPath);`

dir.Refresh();
dir.Delete(true, true);

Alphaleonis.Win32.Filesystem.Directory.Delete(dir.FullName, true); 
Alphaleonis.Win32.Filesystem.Directory.Delete(dir.FullName, true, true);

[Yomodo]

Just to be sure, is the path mentioned in the exception the same path passed to the DirectoryInfo constructor? ("C:\Path\to\Directory") or one of the created sub directories?

Also, does it happen every time, or occasionally?

[LinkForce]

Yes, it is the same path mentioned. And the exception happens every time.

[Yomodo]

I think it's solved.
Could you try branch 490 to see if it fixes the issue?

I could reproduce this issue with the following steps:

After moving the file '$New Text Document.txt' to the root of drive D, I was no longer be able to read its content.

I have discovered the bug when working on raandree/NTFSSecurity#46.

@Yomodo, are you planning to release a new version with fixes or is AlphaFS abandoned?

[itsho]

I think it's already solved.
I was able to reproduce it with 2.2.0 but not with 2.2.6 (current latest)
