Hello. I am not familiar with a device with a Make more Space option, but it could be a brand I am not familiar with.
If you could post a screenshot of your storage page, and let us know what device you are using.
The available space, full or not, is obviously accounting for the operating system space separately, which you may know.
There are file explorer apps like ES File Explorer, if you don't have a built-in app.
This is my 8gb Moto G storage.
