NotADirectoryError: [WinError 267] During load_from_disk
Opened by Grassycup (open)

## Describe the bug
Trying to load saved dataset or dataset directory from Amazon S3 on a Windows machine fails.
Performing the same operation succeeds on non-windows environment (AWS Sagemaker).

## Steps to reproduce the bug
```python
# Followed https://huggingface.co/docs/datasets/filesystems.html#loading-a-processed-dataset-from-s3

from datasets import load_from_disk
from datasets.filesystems import S3FileSystem


s3_file = "output of save_to_disk"

s3_filesystem = S3FileSystem()

load_from_disk(s3_file, fs=s3_filesystem)
```

## Expected results
load_from_disk succeeds without error

## Actual results
Seems like it succeeds in pulling the file into a windows temp directory, as it exists in my system, but fails to process it.
