Hi UnevenDolphin73

I have reproduced the error :
Here is the behavior of that line, according to the version : StorageManager. download_folder( s3://mybucket/my_sub_dir/files , local_dir='./')

1.3.2 download the my_sub_dir content directly in ./
1.4.x download the my_sub_dir content in ./my_sub_dir/ (so the dotenv module cant find the file)

please keep in touch if you still have some issues, or if it helps you to solve the issue
