/Path would be considered an absolute path.
I assume you're working on Windows. In that case "/Text Based RPG/Text Files/" implies C:\Text Based RPG\Text Files (replace C:\ according to situation). To get a path relative to the current working directory (i.e. next to your executable), you simply start with the name.
Code:
├── build
│ ├── install.bat // path: "../install.bat"
│ ├── app
│ │ ├── program.exe // ← your program & (usually) working directory
│ │ ├── config.ini // path: "config.ini" or "./config.ini"
│ ├── data
│ │ ├── blob.bin // path: "../data/blob.bin"
├── README.md // path: "../../README.md"
