"Setup_AWS_CLI_and_S3.md" - problem creating an s3 folder

Question

I was trying to follow steps here:  
  
https://github.com/aws/aws-fpga/blob/master/Vitis/docs/Setup_AWS_CLI_and_S3_Bucket.md  
  
But this suggested step failed for me:  
  
$ aws s3 mb s3:///   # Create folder for your tarball files  
  
Prior to this, I had done this step successfully:  
  
aws s3 mb s3://gurce-fpga-afi  
  
But then I tried the next-suggested line, with:  
  
aws s3 mb s3://gurce-fpga-afi/dcp-tar  
make_bucket failed: s3://gurce-fpga-afi/dcp-tar An error occurred (BucketAlreadyOwnedByYou) when calling the CreateBucket operation: Your previous request to create the named bucket succeeded and you already own it.  
  
I'm starting to suspect that the 'aws s3 mb' command is just for making a bucket, and not for creating a folder.  
  
From what I've learnt about s3 buckets so far, the folder is more of an abstraction that doesn't genuinely exist.  
  
So perhaps I should skip this step and do the steps below it? (And that will implicitly create such a folder?)  
  
$ touch FILES_GO_HERE.txt                          # Create a temp file  
$ aws s3 cp FILES_GO_HERE.txt s3:////  # Which creates the folder on S3  
  
Ok, I tried this, and yep, it seemed to work:  
  
aws s3 cp FILES_GO_HERE.txt s3://gurce-fpga-afi/dcp-tar/  
  
...but still, it seems odd to have that failing step in the instructions, should it be removed?

Answer

Hello,  
  
That's correct, calling s3 mb a second time will not work. Even the following won't work as intended as it just creates the bucket and not the object under the bucket:

```
aws s3 mb s3:/// 
```

I'll update the incorrect instructions right away. Thanks for bringing it to our attention!
