It is within these folders that all files will now be downloaded from the Hub. Caching ensures that
a file isn't downloaded twice if it already exists and wasn't updated; but if it was updated,
and you're asking for the latest file, then it will download the latest file (while keeping
the previous file intact in case you need it again).  
In order to achieve this, all folders contain the same skeleton:  
```
<CACHE_DIR>
├─ datasets--glue
│  ├─ refs
│  ├─ blobs
│  ├─ snapshots
...
```
