## Dificulty
TODO
## How to solve
The main page mentions something about a proprietary format with a store.
The page also mentions that it was created on mac.
Apple has a proprietary file format called "DS_Store" that saves metadata about folders.
If you visit `/.DS_Store`, you find a hidden file.
You can either parse this file using a script, (for example using [this](https://github.com/gehaxelt/Python-dsstore)), or just figure out by looking at the file that there is a folder `0n3_m0re_th1ng`.
Visiting `/0n3_m0re_th1ng` will return the flag.
## Hints
### Hint #1 (medium hint)
I've been looking into proprietary filesystems lately. Interesting stuff.
### Hint #2 (big hint)
I followed this really great workshop on Git last year, but I do wish I had payed more attention to the part about the .gitignore file though. Maybe then my projects wouldn't be filled with random files. I heard GitHub hosts some templates for different operating systems, maybe that can help.
