quickest way to get file/directory sizes

Is there a quicker way to get file sizes (talking tonnes of directories and Gigs of data) then just getFileSize?

you could write a c# assembly but I doubt it will be much faster. Traversing all directories manually is the only way to get a total directory size.

Here is such an example:

This is a most fastest way to get information about file.

(
	fn CREATE_WIN32_FIND_DATA =
		(
			if classof (dotnet.getType "FindDataEx.Kernel32")!=dotNetObject do
			(
				local source=(dotNetClass "System.IO.File").ReadAllText @"YourPath\FindData_Example.cs" (dotNetClass "System.Text.Encoding").Default

				local csharpProvider = dotnetobject "Microsoft.CSharp.CSharpCodeProvider"
				compilerParams = dotnetobject "System.CodeDom.Compiler.CompilerParameters"

				compilerParams.ReferencedAssemblies.Add("System.dll");
				compilerParams.ReferencedAssemblies.Add("System.Data.dll");
				compilerParams.GenerateInMemory = on
				compilerResults = csharpProvider.CompileAssemblyFromSource compilerParams #(source)


				if compilerResults.errors.count == 0 then
					compilerResults.CompiledAssembly
				else
				for f in 0 to compilerResults.errors.count - 1 do (
					print (compilerResults.errors.item[f].ErrorText)
					print ( compilerResults.errors.item[f].Line as string)
					)
			)
		)

	CREATE_WIN32_FIND_DATA()

	-- (dotNetObject "FindDataEx.Kernel32").RecurseDirectory <System.String>directory <System.Int32>level [out]<System.Int32&>files [out]<System.Int32&>folders
	sst = timestamp()

	size = (dotNetObject "FindDataEx.Kernel32").RecurseDirectory @"D:\" (-1) &files &folders
	format "% GB |files: % |folders: %\n" ((size as float)/(1024^2*1024)) files folders

	format "Time: % sec\n" ((timestamp()-sst)/1000.0)
)

Looks really nice. Is this the same method used in windows explorer file properties?

as i know explorer uses something different and it's slow. Track's sample has to beat explorer, but it will be interesting to have comparison: max built-in getfilesize VS system.io.fileinfo VS kernel32 findfirstfile
