Failed to {operation} `{from_name}` to `{to_name}`. A file o

Error message

Failed to {operation} `{from_name}` to `{to_name}`. A file or folder already exists there.

What it means

A rename/move undo or redo failed because the underlying FS rename returned an 'already exists' error (destination occupied), detected by scanning the error chain for an AlreadyExists io error or 'already exists' text.
