Defraggler doesn't seem sum up fragmented directory-entries on the "file list" tab after an analysis. I almost always use that because a full defrag is a waste of time since it easily takes 10 times longer. Anyway, directories don't show up there, so it's not possible to defragment them the manual way.

It seems that directories get defragged only when doing a full defrag...

And since I have a few directories that are constantly being fed with thousands of (contiguous) files, I'd like to defrag them like I can with regular files...

Can this please be added someday?

For the time being thany, you could achieve your aim by using Andavari's reg entry, which puts Defraggler into Windows context menu.

This means you can simply right click a folder, and defrag it.

You won't have the Defraggler GUI, just a Command Line window with a percentage defragged display, but that's worked fine for me for some time now.

Hope that helps until the devs take note of your suggestion.

Does your solution defrag the contents of the directory, or the directory entry itself?
