Back to replacing existing file when rendering?

I accidentally clicked the "do not ask again" box or something, and then hit no when rendering when it asked me to replace a file with the same name already existing in the location folder. And I want it to ask me again, every single time ever, if I want to replace the existing file with the same name, because yes, I do want it to replace it. Now, instead of getting Track Mix replaced at will, I get Track Mix, Track Mix-001, Track Mix-002...

Any ideas? I looked in the options but nothing that could solve this. Thanks!
