Ned a step by step guide to download folder from Amazon S3 with the error unable to locate credentials

Question

Hi

I am new to computers but a friend told me to have my backup in Amazon S3. It worked fine so far but now I need to download a folder from it.

I have installed AWS CLI (and checked that it's working).

I have tried to run the command       aws s3 cp s3://bucket/Folder C:/Folder --recursive   but I get the response: unable to locate credentials.

Now I don't know what to do. I guess i need to make a profile in CLI but how? And shuldnt it be loaded in the command to copy the folder? Think I need some step-by-step guidiance :)
