Tell the user which file cannot be updated

[Pebl]

I'm changing the time/date of all files in a folder

Sometimes the error occurs that one/some? files cannot be updated.
It would be helpful to have the information which file(s) cannot be updated, because the second try mostly works. So I can just select the missing files and I do not have to wait for hundreds of files being written in vain

Thanks to your detailed description I can reproduce the problem.
