DeleteEmptySubdirectories (with recursive=true) throws System.IO.DirectoryNotFoundException

[kryvoplias]

Hi all,

I'm trying to delete all empty directories and sub-directories by using Directory.DeleteEmptySubdirectories with recursive flag.

But I'm getting exception System.IO.DirectoryNotFoundException with following message: "(3) The system cannot find the path specified: [\?\c:\temp\test\Foo\FooBar*]"

To reproduce, create following folders (Powershell):

New-Item -ItemType Directory c:\temp\test
New-Item -ItemType Directory c:\temp\test\Foo
New-Item -ItemType Directory c:\temp\test\Foo\FooFoo
New-Item -ItemType Directory c:\temp\test\Foo\FooBar
New-Item -ItemType Directory c:\temp\test\Bar

Then execute:

[Alphaleonis.Win32.Filesystem.Directory]::DeleteEmptySubdirectories("c:\temp\test", $true)
// even after exception all folders get deleted except C:\Temp\test\Foo.

Unhandled Exception: System.IO.DirectoryNotFoundException:

If execute this again:

[Alphaleonis.Win32.Filesystem.Directory]::DeleteEmptySubdirectories("c:\temp\test", $true)
// after second exception all folders in C:\Temp\test are now deleted.

Confirmed.
It seems that the upcoming v2.1.3 release fixes this bug.

Update: The fix will be in v2.2

[kryvoplias]

Seems like this bug is now fixed in 2.1.3

[Yomodo]

Weird, I still get a DirectoryNotFoundException.

[kryvoplias]

That's really weird. After updating to v2.1.3 everything was OK, but after reboot tests became red again.
