I know they are all the negative form of a verb, but I just don't know the
difference. I still remember when I was learning Japanese, my teacher told me
that ずに equals ないで in a more ancient way, but what about the other two? When
should I use ないで, and when should I use なくて? And how about ず? Thank you.

question
grammar
The difference among ずに、ず、ないで、なくて
なくて stands for a causal connection, that is, できなくて やめた means that you quit
because you couldn't, while できないで やめた means that you quit it without
accomplishing it.

ず can be interchangeable to either ずに（ないで） or なくて.
