1. Make sure not to forget the `/` behind the folder, ![](https://hackmd.io/_uploads/Sk5ekt42n.png) or you'll get a weird redirection like this ![](https://hackmd.io/_uploads/H1dHAuEh2.png) 2. According to Hint: *folder folder folder*, the flag is probably stored in the deeper folder![](https://hackmd.io/_uploads/SJiOhOV32.png)So I go to `http://saturn.picoctf.net:62050/secret/` 3. In `http://saturn.picoctf.net:62050/secret/`, we can see that there's another `hidden` folder![](https://hackmd.io/_uploads/HkQChO4nh.png)So let's apply the same method: `http://saturn.picoctf.net:62050/secret/hidden/`![](https://hackmd.io/_uploads/SJX5pu4hh.png) 4. Then `http://saturn.picoctf.net:62050/secret/hidden/superhidden/`![](https://hackmd.io/_uploads/Bywapu4nh.png)Here we go the flag!
