Is this conversation right
Have you seen x
No I did't see x
Did you get the file
Yes I got it
Thanks
Have you seen x - correct
No I didn't see x - OK, but it would be more correct to reply to 'Have you seen x' with 'No, I haven't seen x', or 'No, I haven't seen him/her'
Did you get the file - correct
Yes I got it - correct
Hi,
Don't forget the punctuation. A comma, as already pointed out, and also a period and a question mark, eg
Did you get the file?
Yes, I got it.
Best wishes, Clive
