There might be no easy fix for the root cause: Windows does not distinguish such file names.Error, two files with the same name but different case exist on the remote server!
Because Windows doesn't support this on local drives, you need to delete one of the duplicates before proceeding!
res\-e.xml
res\-E.xml
But there is a smaller one - both files were on local NTFS disks and no remote servers were involved.
Please see if the wording of the message should be changed.
