a) Ok sir, I will send you that file tomorrow. (Definitely)
b) Ok Sir, I would send you that file tomorrow. (Probably)
In above sentences can we use Will interchangeably and imagine the meaning given in bracket?
Sentence a) Indicate that I will definitely send him file.
Sentence b) Indicate that I would send him file if I found It.
I am aware that would is mainly use as past tense for will but my question is for future tense. Can we use Would to talk about future?
