Show subfolders in archives

[romulous]

Does anyone know of a way - either via TC itself or even I suppose by a plugin (for example custom columns) - that TC can show if an archive file (zip, rar) has a subfolder? What I want to do is identify visually the difference between the following two archive files without actually having to go into them to manually check:

Archive
-File1
-File2
-File3

Archive
-Folder
--File1
--File2
--File3

Obviously if I double click on them in TC, I can see if the files are in a folder or not, but I am tired of having to do this, and want something similar to the old file manager in Windows 3.1 (that is, it showed a + sign next to folders that had sub-folders).

Total7zip ( http://www.totalcmd.net/plugring/total7zip.html ) installed and configured as a content plugin shows number of files and folders inside archive files.

Hm, doesn't seem to want to work as anything but a packer plugin here.

Read included readme files (readme.rtf).
You must manually edit INI file or enable view *.wcx files during installation (through TC interface) by typing *.wcx in "Open" dialog window, or copy Total7zip.wcx to Total7zip.wdx
Plugin works as a simple Lister plugin as well!

or copy Total7zip.wcx to Total7zip.wdx

Ah, that did it (why the dev just didn't include a wdx file, who knows). After all that - it failed at the first hurdle I am afraid. After installing, I opened the folder containing a test file, and it reported that it had 4 folders. Well, it only has three, but we will ignore that error. The main problem is this:
Test.zip
-Folder1
-Folder2
-Folder3
--File1
--File2
--File3

So, it still doesn't tell me that the files are not in a sub-folder I am afraid (which is what I want to know).
