For a detailed, more precise answer, please read the EULA here.

If you don't like those kinds of texts, here is the tl;dr version:
For personal, non-commercial purposes, yes, it can be downloaded, installed, and used free of charge. For any other purposes, you have to pay for it. The rule of thumb, on figuring out if it is free for you or not, is to answer this question: Will I receive money for the task Zen Commander helps me accomplish? If yes, you most likely should pay for it. If not, it is still free for you. If you still cannot decide whether you may use it freely or not, please read the license category in our FAQ, or contact us.
