Appelle-moi quand tu auras fini?
I want to say the following sentence in French "Call me when you have finished."
However, I know I can't use futur interieur, nor conditonnel passe,

so what is the mode/tense I should use.

Quand tu auras fini, appelle-moi?

Quand tu auras fini, appelle-moi?

Answer

Yes, that's perfect!

In English, the sentence would be "Call me when you're finished", not "when you have finished".

Note also that "quand tu auras fini" is the futur **antérieur**, not intérieur. :)

Answer

In this case you don't have to use le futur anterieur because the action of calling is in the present. Je pense que ça doit être comme ça: Appelle-moi quand tu finira. remenber to use le futur antérieur quand on emploie futur simple. à tantôt!

Answer

Oui c'est correct, "Appelle-moi quand tu auras fini"
