How can you create a .aws folder? [duplicate]

It says specifically in this AWS readme documentation to make a .aws folder, and other folders of this type exist (.ext), but windows says "you must type a file name" in order to try and create a folder like this and won't let you.

I could be reading this wrong, so correct me if I am. The \ is confusing and I am used to seeing this in commenting code, but not in actual file folders.

You need to set up your AWS security credentials before the sample code is able
to connect to AWS. You can do this by creating a file named "credentials" at ~/.aws/ 
(C:\Users\USER_NAME\\.aws\ for Windows users) and saving the following lines in the file:

[default]
aws_access_key_id = <your access key id>
aws_secret_access_key = <your secret key>

Solution 1:

Normal DOT before a file denotes hidden file or folder(in Linux and OSX).

If you wanted to create a folder name with DOT a front like ".aws" then while naming the folder use a dot at the end too ".aws.". windows will automatically remove the dot at the end and keep the folder name as ".aws"
