How do I duplicate a save file?

[☀ Dawnheart ☀]

So on save 1 I've unlocked everything. And I want to copy this file for my own use. How do I do that? It's on my desktop, I have Windows 10 (if that's a factor) and have I been living under a rock?

I'll try my best, not sure if this works, but, send the file to yourself via email, download the file from your email, Make sure the file you sent to yourself ISN'T already in your Downloads folder, this may make it difficult. Go to that file, and rename it "WarriorsSaveTwo" or "WarriorsSaveThree" It IS Case sensitive, hope this helps, if you need further explanation let me know ☀ Dawnheart ☀
