I'm sorry but I am not sure what the situation is or what the question is.
Can you restate the question in other terms please?
I would say one thing. I try to avoid multiple file copying from several folders to several folders at the same time. It might overtax the CPU and RAM, and if one of the copying processes falters and fails, then you could lose a lot of work.
I 'think' what you are asking is this. When you hover the mouse over the folder icons in the Taskbar, you see the "File Copy" progress bar in each. That is to be expected, but if the file copy progress bar is displayed for any length of time then that would mean you are doing an awful lot of file copying.
During multiple file coping(file transferring) from one folders to other folders while minimizing all the folder at the time, check the status in taskbar, it showing all folder as file coping folder. is it expected in aero themas or its issue.
