AllSync & AllDup

Hi all,
I recently registered as I have been using AllDup for a few years now. The last few times I've marked duplicate files for removal, it's beyond slow then notice a great deal of them are not removed. What am I doing wrong?
It's for my PC and I use Windows 10.
Thanks in advance.

Post the log of the deletion action here in the forum or send us the log by e-mail.

then notice a great deal of them are not removed

Was a reason given as to why?
