I am using Multi Commander 10.2.0 (Build 2745) portable version.
When I create a new folder, the folder has 0 byte. When I copy this 0 byte folder to another path (click F4 on the keyboard), the copied 0 byte folder is set to current time. Of course in the copy window I have selected the option that the timestamp must be kept.
When I do the same with files or folders with files there are no problems.
It is a bug.
