Hi Dmitriy,

I prefer using the AWS CLI commands via the BASH component to achieve this. Here’s a single line to do what you are after -

aws s3 rm s3://mybucket/myfolder/ETLWork/ —recursive

More information on this at the following link –
Needless to say, please test this on a safe location to gain some confidence :)

If you are keen to go down the Python+boto route, the following link seem to have an example for the same.

Hope that helps.

I already have a Jython script. I don't want to call BASH script in the middle of Python script.
Your example is "How to delete folder and its content in a AWS bucket using boto3". I don't want to delete folder.

Hey Dmitriy;

Try this.

import boto
def delete_s3_recursive(bucketname, keyprefix):
s3 = boto_connect_s3()
bucket = s3.get_bucket(bucketname,validate=False)
bucketListResultSet = bucket.list(prefix=keyprefix)
return bucket.delete_keys([ for key in bucketListResultSet])

Given the two parameters, bucketname and keyprefix (the filename mask for targeted files), this should do what you are hoping. Bear in mind your credentials must support the activity for the given bucket/files.

Good Luck,

Edward Hunter

I am using boto3, not boto
"AttributeError: 's3.ServiceResource' object has no attribute 'get_bucket'"

How can I do this with boto3?

Thank you,

This boto3 code delete all files and folders. I would like to delete only files.
s3 = boto3.resource('s3')

BucketW = s3.Bucket('BUCKET')
BucketW.objects.filter(Prefix = 'ETLWork').delete()

BucketW = s3.Bucket(BUCKET)
for obj in BucketW.objects.filter(Prefix = ETLWork):
if '.txt' in obj.key:
