Save compressed files in file system

I want to save multiple files in one Zip file on my disc. This Zip is created but his type is "Compressed (zipped) Folder" and is impossible to open. Error: "Windows cannot open the folder. The Compressed (zipped) Folder 'path' is invalid. Can I make it normal .Zip file somehow?

int i = 0;
await using var ms = new MemoryStream();
    using var archive = new ZipArchive(ms, ZipArchiveMode.Create, true);
        foreach (var s in stepwiseData)
            var entry = archive.CreateEntry($"Name {i.ToString()}");
            using (BinaryWriter writer = new BinaryWriter(entry.Open()))
        var folder = @"C:\Temp\test\";
        var fileName = "";
        var fullPath = folder + fileName;

        var bytes = ms.ToArray();
        File.WriteAllBytes(fullPath, bytes);
