Faster way to count all files and directories in specific path?

#1

I am trying to count all files and directories in specific path with a faster way,there is already a solution with c# code:

private static long SizeOf(string directory)
    {
        var fcounter = new CSharpTest.Net.IO.FindFile(directory, "*", true, true, true);
        fcounter.RaiseOnAccessDenied = false;

        long size = 0, total = 0;
        fcounter.FileFound +=
            (o, e) =>
            {
                if (!e.IsDirectory)
                {
                    Interlocked.Increment(ref total);
                    size += e.Length;
                }
            };

        Stopwatch sw = Stopwatch.StartNew();
        fcounter.Find();
        Console.WriteLine("Enumerated {0:n0} files totaling {1:n0} bytes in {2:n3} seconds.",
                          total, size, sw.Elapsed.TotalSeconds);
        return size;
    }

The question is,is there a same solution in maxscript?

Actually I’ve build the c# source to a dll file from here to try to work:

Unfortunately I stucked,I don’t know what’s the means,does anyone can help?Thanks in advance.

mxs is more efficient for this , most time , not all time

(
	st = timestamp()
	yourpath = @"....."
	sel=#(#(),#())
	fn getFilesRecursive p  =
	(
	    allpath = GetDirectories (p+"/*")
    	join sel[1] allpath
    	join sel[2]  (getFiles (p +"/*.*" ))
    	for i in allpath do 
			getFilesRecursive i
	)
	getFilesRecursive  yourpath
	format " %ms  %dirs  %files\n" (timestamp()-st) sel[1].count sel[2].count
)

dotnet can get all path and files , it is a Double-edged sword , some paths are denied to access , such as “System Volume Information” , try to get files in it will cause runtime error, you can use try to avoid ,but more slow
if the path is a very large path such as root “c:” , dotnet faster than mxs

(
    st = timestamp()
    cl=dotnetclass "System.IO.Directory"
    yourpath = @"....."
    sel=#(#(),#())
    fn getallfiles p =
    (
        allpath = cl.GetDirectories p
        join sel[1] allpath
        join sel[2] (cl.getFiles p)
        for i in allpath do 
            getFilesRecursive i
    )
    getallfiles  yourpath
    format " %ms  %dirs  %files\n" (timestamp()-st) sel[1].count sel[2].count
)

if just get count , change sel to #(0,0) ,and change the function “join” lines to sel[1]+=allpath.count and sel[2]+= (…).count

by @Swordslayer
The getFiles() and getDirectories() methods have a recurse: parameter to indicate whether to recursively search for files or directories.

Thanks for your great help and suggestion!
