"Qual é a minha janela?"

Translation: Which one is my window?

[mn3mGAVE]

I don't see that "what" would be a wrong choice here. It may be used as well as "which" in normal english to mean the same thing here.

[PaulAbraha11]

I wouldn't agree with that - this is one case, unless you're trying to determine whether it's glass or plastic, for example, where the translation is definitely which [one].

[Ann493968]

Not good english to say "what is my window" in this context ......you know what the window is,but you need to know which window it is.

[drewarnold72]

How do you know when "Qual" means "what" and when it means "which"?

For example, "Qual é a minha janela?" means "Which one is my window?", whereas "Qual é a ocupacao dela?" means "What is her occupation?"

This discussion thread definitely helped, especially the Youtube video link provided by r_i_l_e_l_y. Although the video is about the difference between "Que" and "Cual" in Spanish, it seems to also apply to BP. For example, in both of the sentences I provided above as examples of "qual" meaning what or which, in both cases there is a limited number of possible answers, which according to the video is one of the usage rules about when to use "Qual" vs. "Que".

SO, WHAT IS THE ANSWER (difference) "???

[MorenaPaulista]

Which one's my window is also the correct English translation. One's = short form of "one is". I don't know why that answer is not acceptable.

[Jandreslami]

Would "Qual é minha janela?" be correct?

[Paulenrique]

yes!

[Viljou]

But I think that would mean: "Which is my window?" Right?

[TimTobish]

The one is superfluous. Which is my window is also correct.

[nHontas]

how many meanings does the Portuguese word "Qual" have?!

[Monica514249]

In american english we would say "which one is my window?" or "which window is mine?" Almost never would we say "which is my window?"
