Is it possible to group folders together at the top on Unity for MacOS? (Like on Windows)

Question

Pretty straight forward...

On Windows folders are sorted together at the top of the file list before their sibling files in the same folder.

I have found the Finder setting to accomplish this, which works for Finder, but it has no effect on how Unity operates: https://lifehacker.com/sort-folders-and-files-on-mac-just-like-windows-with-a-1788709887

I also found a forum post from 2013 with an extension that is designed to fix this. However despite fixing the missing "&" symbols in the script, it still does not seem to work: https://forum.unity.com/threads/project-window-extension-script-folders-sorting-double-click-expand-collapse.180186/

I ALSO found a Unity Answers question on this from 2015, to which the first response came from me, today, 4.5 years later: https://answers.unity.com/questions/991484/project-view-folder-grouping-in-osx.html

REALLY hoping someone can help me out here because it's driving me insane.

i'm also looking for the same thing. this folder-file sorting is killing my production speed.

Sorry to raise this post, but had to tweak some of the code to get it to work, thought I would share.

thank you @WeslomPo for the original!

Hi @NMD83 ! How are you?

So, problem lay here

```

 // not actually code
 //        foreach browser in UnityEditor.ProjectBrowser.s_ProjectBrowsers
 //            browser.m_AssetTree.data.foldersFirst = true
 //            browser.m_ListArea.foldersFirst = true

         EditorApplication.projectWindowItemOnGUI += OnFirstTime;
     }

     private static void OnFirstTime(string guid, Rect selectionrect)
     {
         EditorApplication.projectWindowItemOnGUI -= OnFirstTime;
         Refresh();
     }

     private static void OnChanged() => Refresh();

     private static void OnPlayMode(PlayModeStateChange obj) => Refresh();
     /// <summary>
     /// По сути, присваиваем значение определенной переменной:

     private static void Refresh()
     {
         var assembly = Assembly.GetAssembly(typeof(Editor));
         var projectBrowser = assembly.GetType("UnityEditor.ProjectBrowser");
         var field = projectBrowser.GetField("s_ProjectBrowsers", BindingFlags.Static | BindingFlags.NonPublic);

         if (field == null)
             return;

         var list = (IEnumerable) field.GetValue(projectBrowser);
         foreach (var pb in list)
             SetFolderFirstForProjectWindow(pb);
     }

     private static void SetFolderFirstForProjectWindow(object pb)
     {
         var members = pb.GetType().GetRuntimeFields();
         foreach (var member in members)
             switch (member.Name)

                     SetTwoColumnFolderFirst(pb, member);
                     break;
             }
     }

     private static void SetTwoColumnFolderFirst(object pb, FieldInfo listAreaField)
     {
         if (listAreaField == null)
             return;
         var listArea = listAreaField.GetValue(pb);
         var folderFirst = listArea.GetType().GetProperties().Single(x => x.Name == "foldersFirst");
         folderFirst.SetValue(listArea, true);
     }

     private static void SetOneColumnFolderFirst(object pb, FieldInfo assetTreeField)
     {
         if (assetTreeField == null)
             return;

         var assetTree = assetTreeField.GetValue(pb);
         var data = assetTree.GetType().GetRuntimeProperties().Single(x => x.Name == "data");
         // AssetsTreeViewDataSource
         var dataSource = data.GetValue(assetTree);
         var folderFirst = dataSource.GetType().GetProperties().Single(x => x.Name == "foldersFirst");
         folderFirst.SetValue(dataSource, true);
     }
 }

Is it possible to group folders together at the top on Unity for MacOS? (Like on Windows)
