In the past I was used to robocopy plaining for errors and continually retrying if the file in the destination existed and was open and couldn't be overwritten therefore. Today I asked myself why the files at the destination were not updated and found that robocopy counts the open files in its summary error column, but doesn't do any retry.

It seems to me that this is a bug. Or is this intended behavior change?
Where could I report this bug?

This is on Win 10 Version 2004 (Build 19041.572)

Answer 1

Hey, I'm experiencing the same issue here. Any information?

Answer 2

We are also waiting for some answer. Still no hints?

Answer 3

I was forced to use robocopy.exe from older windows version. Please fix this.

Answer 4

I have the same problem. I think since the 2004 update robocopy does not retry anymore.

Answer 5

We had the same issue. We use robocopy because of its retry ability if it is not working it just not suitable any more...
