While I was experimenting in order to have more details for the other problem, EDP got locked: no hourglass turning, no light beam movement on the progress bar, no change for more than 10 minutes, Windows saying "no response" (as you can see in the screenshot).
Pressing <esc> or clicking the <cancel> button only gets a dialog from Windows saying "It doesn't respond".
I saw this effect a few other times, but this is the first time it's reproducible: always 64%.

By the way, I'm quite mean: to have a lot of files to show I compared the c:\Windows directory (and subdirs) with itself.

Please create a process memory dump (you can use, for example, Process Explorer (from Microsoft's SysInternals suite), or even the Task Manager. In both apps right-click on the process and select Create Dump or similar), then send the dump to us.

No, sorry, it's not really hanging. It's just ignoring the OS.
After having left it alone for many minutes it was finished...

Still would be beneficial to know what was taking so long.

Thanks for the process dumps. It turns out, the slow-downs are mostly due to the huge number of items to sort. One thing that will make things faster is if you did not use the "Show empty directories in recursive comparison" option.

Like having to resort to a sort merge with partial files?

Quite surprising!
After all, an empty directory should be just a single more item to sort together with 300,000 other items.

Sorry for the bothering.

Empty directories are bunched together during sorting, hence a need to determine the "emptiness". And that takes time.
