Syntax error on renaming file

[Davide]

In Italian I get the "Errore di sintassi - Impossibile analizzare l'indirizzo del server: Nessun host fornito, inserisci un host." error (theoretically in English it would be similar to "Syntax error - Failed to parse server address: No host provided, please enter a host.") when I rename a file locally in FileZilla when a file with the same name already exists.

Then the message "Impossibile rinominare il file, Errore imprevisto, Se l'errore persiste, è possibile utilizzare il codice errore per cercare ulteriori informazioni sul problema. Errore 0x80070057: Parametro non corretto.".
In English it should be something like: "Failed to rename file, Unexpected error" also appears. If the error persists, you can use the error code to look for more information about the problem. Error 0x80070057: Incorrect parameter."

In my opinion it would be enough to warn that a file with the same name already exists.
