I'm finished

can I say "I'm finished" when I have finished doing sth, and, for instance, sb is waiting to use the device I've been using

tak, ale lepiej ...'I 'have' finished', alebo 'I've finished'

dzieki, ale na pewno jest coś takiego 'I'm finished'?

yes, yes it is possible to use it but more in spoken English and everyday English

a gdzie ty to znalazlas?.

We use it all the time, terri. Również I'm done. W pytaniach też: Are you finished? Are you done?

It's very casual though.

zgadzam sie z tym, ale dla mnie to nie jest jezyk, ktory powinnismy uzywac w pracy....'somebody is waiting to use the device I've been using'.

a mogę spytać gdzie tego się używa? mieszkasz w UK czy w stanach?

I'm finished......Jestem skonczony. Koniec ze mna.
I've finished - skonczylem to co robilem.

Terri, a
I'm finished with these files brzmi dla Ciebie naturalnie?

Quoting bbc.co.uk

See what you think:

Mum to kid eating - Have you finished?
Teacher to student - Have you finished?

Some people would argue that using the present perfect tense and forming the question ‘Have you finished?’ seems to politely give the possibility of more time to finish, whereas 'Are you finished?’ lets the person know they are nearly out of time and no more is available.
Well, personally, I think tone of voice is the all important aspect here. You can express impatience or politeness just from the manner in which you say either of these questions:

Have you finished? Are you finished? (that was my impatient voice)
Have you finished? Are you finished? (that was my polite voice)

Well I hope you could hear the differences there and that you are successful sounding polite or impatient depending on the situation that you’re in!

So it all depends on whether you want to be polite or whether you want to emphasize the fact that time has run out.
