Renaming Folders And Using File Count

I Have Been Trying To Figure Out How To Rename Folders And Using The File Information Fields But It Is Not Working

I Would Like

C:\My Folder\MySub Folder 1
C:\My Folder\MySub Folder 2

To Look Something Like This

C:\My Folder\MySub Folder 1 (Total Files = 2890)
C:\My Folder\MySub Folder 2 (Total Files = 6526)

That Would Give Me The Number Of Files In That Folder And All Sub Folders.

Can It Be Done?

I don't think the sub-file/folder-count fields work when renaming.

I've filed a bug report, though I don't know if the fix will be to make them work in the rename dialog or to remove them from the menu in the rename dialog. It could be that they're not suppose to work but are listed by mistake.
