Add folder in Amazon s3 bucket

This is a divisive topic, so here is a screenshot in 2019 of the AWS S3 console for adding folders and the note:

When you create a folder, S3 console creates an object with the above name appended by suffix "/" and that object is displayed as a folder in the S3 console.

Then 'using coding' you can simply adjust the object name by prepending a valid folder name string and a forward slash.

Here's how you can achieve what you're looking for (from code/cli):

--create/select the file (locally) which you want to move to the folder:

~/Desktop> touch file_to_move

--move the file to s3 folder by executing:

~/Desktop> aws s3 cp file_to_move s3://<path_to_your_bucket>/<new_folder_name>/

A new folder will be created on your s3 bucket and you'll now be able to execute cp, mv, rm ... statements i.e. manage the folder as usual.

If this new file created above is not required, simply delete it. You now have an s3 bucket created.

Below creates a empty directory called "mydir1".

Below is nodejs code, it should be similar for other languages.

The trick is to have slash (/) at the end of the name of object, as in "mydir1/", otherwise a file with name "mydir1" will be created.

let AWS = require('aws-sdk');
AWS.config.loadFromPath(__dirname + '\\my-aws-config.json');
let s3 = new AWS.S3();

var params = {
    Bucket: "mybucket1",
    Key: "mydir1/",
    ServerSideEncryption: "AES256" };

s3.putObject(params, function (err, data) {
    if (err) {
        console.log(err, err.stack); // an error occurred
        return;
    } else {
        console.log(data);           // successful response
        return;
        /*
         data = {
         ETag: "\"6805f2cfc46c0f04559748bb039d69ae\"",
         ServerSideEncryption: "AES256",
         VersionId: "Ri.vC6qVlA4dEnjgRV4ZHsHoFIjqEMNt"
         }
         */
    } });

I guess your query is just simply creating a folder inside folder(subfolder). so while coping any directory data inside a bucket sub folder use command like this.

aws s3 cp mudit s3://mudit-bucket/Projects-folder/mudit-subfolder --recursive

It will create a subfolder and put ur directory contents in it. Also once your subfolder data gets empty. Your Subfolder will automatically gets deleted.

You can use copy command to create a folder while copy a file.

aws s3 cp test.xml s3://mybucket/myfolder/test.xml
