In our TFS build system, I've added a custom step for deleting the old source code before starting a new build, which needs to be custom because we're using npm which creates folders past the long path limit. I've successfully used AlphaFS for this, but it was taking a long time, so it looked like QuickIO would fit our needs better. However, when switching to use QuickIO, I'm getting an UnauthorizedAccessException. I don't get a similar exception from AlphaFS or from plain System.IO usage, so it seems as though there's something different that QuickIO is doing that's triggering the exception.

My code is a very straightforward recursive delete, passing in a string for the path:
SchwabenCode.QuickIO.QuickIODirectory.Delete(directory, true)
Here's the full stack trace:
System.UnauthorizedAccessException: Access to 'C:\Builds\1\ACR\CI (ACR)\src\.eslintrc' denied. ---> 
System.ComponentModel.Win32Exception: Access is denied --- End of inner exception stack trace --- 
at SchwabenCode.QuickIO.Internal.InternalQuickIOCommon.NativeExceptionMapping(String path, Int32 errorCode) at SchwabenCode.QuickIO.Internal.InternalQuickIO.DeleteFile(String path) at SchwabenCode.QuickIO.Internal.InternalQuickIO.DeleteDirectory(QuickIODirectoryInfo directoryInfo, Boolean recursive) 
at SchwabenCode.QuickIO.Internal.InternalQuickIO.DeleteDirectory(QuickIOPathInfo pathInfo, Boolean recursive) 
at Engage.BuildProcess.Activities.DeleteDirectory.AttemptDelete(CodeActivityContext context, String directory, Int32 tries)
Any thoughts on anything I could do differently, or what might be causing the error?

Hi. Can you give me all attribute information that are assigned to the file?
C:\Builds\1\ACR\CI (ACR)\src.eslintrc

It's marked as "ReadOnly, Archive"

There was a bug a few versions ago, that I've missed to remove the attributes.
Which version are u using? The newest?

Let me know this and I'll check that again. Maybe there is something that I've missed in my tests.

This is my test to validate delete with file attributes.
      [TestMethod( )]
        public void File_Readonly_Delete_Test( )
            using ( var prov = new RandomTestFileProvider( ) )
                var file = prov.CreateRandomTestFile( );

                Assert.IsTrue( File.Exists( file ), "Created test file does not exists (SystemIO)." );

                File.SetAttributes( file, FileAttributes.ReadOnly );

                var attributes = File.GetAttributes( file );
                Assert.IsTrue( attributes.HasFlag( FileAttributes.ReadOnly ) );

                QuickIOFile.Delete( file );

                Assert.IsFalse( File.Exists( file ), "File still exists after delete." );
QuickIOFile.Delete( file ); removes all attributes (sets to "Normal").

Thanks, the beta release seems to have fixed the issue. I appreciate you looking into it for me.
