I've been interacting with Amazon S3 through S3Fox and I can't seem to delete my buckets. I select a bucket, hit delete, confirm the delete in a popup, and... nothing happens. Is there another tool that I should use?
Delete Amazon S3 buckets? [closed]
I ended up using Cyberduck where there's a Windows and a Mac version :) –
Teachin
Using the AWS ruby SDK you can do it in 1 command (bucket.delete!) docs.aws.amazon.com/AWSRubySDK/latest/frames.html#!AWS.html –

It is finally possible to delete all the files in one go using the new Lifecycle (expiration) rules feature. You can even do it from the AWS console.
Simply right click on the bucket name in AWS console, select "Properties" and then in the row of tabs at the bottom of the page select "lifecycle" and "add rule". Create a lifecycle rule with the "Prefix" field set blank (blank means all files in the bucket, or you could set it to "a" to delete all files whose names begin with "a"). Set the "Days" field to "1". That's it. Done. Assuming the files are more than one day old they should all get deleted, then you can delete the bucket.
I only just tried this for the first time so I'm still waiting to see how quickly the files get deleted (it wasn't instant but presumably should happen within 24 hours) and whether I get billed for one delete command or 50 million delete commands... fingers crossed!
just to follow up on this, it worked perfectly, all the files were deleted within 24 hours and we were not even billed for any deletion requests as far as I can see. This is the definitive solution to the problem! –
Clodhopping
This I like. Much better than installing tools, finding out they can't cope with some aspect of my bucket, and repeating... –
Bahuvrihi
Just wanted to say thank you for this solution. A simple upvote cannot express how grateful I am. Works brilliantly. –
Prolate
I've been installing all sorts of command line tools to help delete millions of files from a bucket. This simple solution is the best. Thank you! –
Druggist
Awesome! Much thanks. One vote up! One small change. When you go in the rules window now, they have a checkbox to explicitly apply the rule to the entire bucket. It will not let you leave the Prefix field blank now. –

I had a process that over the years accidentally generated more 1k files that any client could list within a reasonable amount of time, much less delete. This answer literally solved an unsolvable problem. –
Prodigal
FYI, this will not work for buckets with versioning enabled (or even suspended)! –
Dunstan
If you have versioning enabled here is how to delete all the versions so that you can then use the life-cycle rules to delete the existing objects. boulderapps.co/post/… –
Kile
old question I know, but for others they may find this useful... using the
aws cli a single command can do recursive removal of all files: aws s3 rm s3://bucket/folder/ --recursive –
Chaldron @futureSPQR That's fine if you're in the 10-100k range of assets to delete. It would take ages (and cost a lot of delete requests) to remove millions of assets. In my case the lifecycle method was faster and more reliable –
Hillhouse
how to add lifecycle rule using s3cmd? –
Pummel
I couldn't get the lifecycle method to work for me (stuff just never got deleted), but I was able to delete a 100k+-file bucket using the AWS CLI with
aws s3 rb s3://bucketname --force. It wasn't instantaneous but the CLI seems relatively speedy to me. –
Grouse Remeber that S3 Buckets need to be empty before they can be deleted. The good news is that most 3rd party tools automate this process. If you are running into problems with S3Fox, I recommend trying S3FM for GUI or S3Sync for command line. Amazon has a great article describing how to use S3Sync. After setting up your variables, the key command is
./s3cmd.rb deleteall <your bucket name>
Deleting buckets with lots of individual files tends to crash a lot of S3 tools because they try to display a list of all files in the directory. You need to find a way to delete in batches. The best GUI tool I've found for this purpose is Bucket Explorer. It deletes files in a S3 bucket in 1000 file chunks and does not crash when trying to open large buckets like s3Fox and S3FM.
I've also found a few scripts that you can use for this purpose. I haven't tried these scripts yet but they look pretty straightforward.
RUBY
require 'aws/s3'
AWS::S3::Base.establish_connection!(
:access_key_id => 'your access key',
:secret_access_key => 'your secret key'
)
bucket = AWS::S3::Bucket.find('the bucket name')
while(!bucket.empty?)
begin
puts "Deleting objects in bucket"
bucket.objects.each do |object|
object.delete
puts "There are #{bucket.objects.size} objects left in the bucket"
end
puts "Done deleting objects"
rescue SocketError
puts "Had socket error"
end
end
PERL
#!/usr/bin/perl
use Net::Amazon::S3;
my $aws_access_key_id = 'your access key';
my $aws_secret_access_key = 'your secret access key';
my $increment = 50; # 50 at a time
my $bucket_name = 'bucket_name';
my $s3 = Net::Amazon::S3->new({aws_access_key_id => $aws_access_key_id, aws_secret_access_key => $aws_secret_access_key, retry => 1, });
my $bucket = $s3->bucket($bucket_name);
print "Incrementally deleting the contents of $bucket_name\n";
my $deleted = 1;
my $total_deleted = 0;
while ($deleted > 0) {
print "Loading up to $increment keys...\n";
$response = $bucket->list({'max-keys' => $increment, }) or die $s3->err . ": " . $s3->errstr . "\n";
$deleted = scalar(@{ $response->{keys} }) ;
$total_deleted += $deleted;
print "Deleting $deleted keys($total_deleted total)...\n";
foreach my $key ( @{ $response->{keys} } ) {
my $key_name = $key->{key};
$bucket->delete_key($key->{key}) or die $s3->err . ": " . $s3->errstr . "\n";
}
}
print "Deleting bucket...\n";
$bucket->delete_bucket or die $s3->err . ": " . $s3->errstr;

Hope this helps!
I had problems with the aws/s3 gem as I have a european region. Solved by using the s3 gem - github.com/qoobaa/s3 –
Alphorn
The solution from chris14679 (below) that uses lifecycle expiration rules is now the preferred method. –
Corves
This answer has the most upvotes, but it cannot possibly compete with the simplicity of @Clodhopping 's comment below. I just deleted several million files in under 10 clicks and maybe 10 key strokes. Beautiful simplicity. –
Druggist
recent versions of s3cmd have --recursive
e.g.,
~/$ s3cmd rb --recursive s3://bucketwithfiles
With s3cmd: Create a new empty directory s3cmd sync --delete-removed empty_directory s3://yourbucket
This may be a bug in S3Fox, because it is generally able to delete items recursively. However, I'm not sure if I've ever tried to delete a whole bucket and its contents at once.
The JetS3t project, as mentioned by Stu, includes a Java GUI applet you can easily run in a browser to manage your S3 buckets: Cockpit. It has both strengths and weaknesses compared to S3Fox, but there's a good chance it will help you deal with your troublesome bucket. Though it will require you to delete the objects first, then the bucket.
Disclaimer: I'm the author of JetS3t and Cockpit
SpaceBlock also makes it simple to delete s3 buckets - right click bucket, delete, wait for job to complete in transfers view, done.
This is the free and open source windows s3 front-end that I maintain, so shameless plug alert etc.
Wow. Thanks for the reference to SB. Worked great, and I didn't have to install FireFox to acomplish deleting S3 buckets. –
Minardi
Didn't work for me for some reason. But great tool for browsing buckets. Maybe add an option "delete everything" as well. –
Betts
I've implemented bucket-destroy, a multi threaded utility that does everything it takes to delete a bucket. I handle non empty buckets, as well as version enabled bucket keys.
You can read the blog post here http://bytecoded.blogspot.com/2011/01/recursive-delete-utility-for-version.html and the instructions here http://code.google.com/p/bucket-destroy/
I've successfully deleted with it a bucket that contains double '//' in the key name, versioned key and DeleteMarker keys. Currently I'm running it on a bucket that contains ~40,000,000 so far I've been able to delete 1,200,000 in several hours on m1.large. Note that the utility is multi threaded but does not (yet) implemented shuffling (which will horizontal scaling, launching the utility on several machines).
This is well-implemented code that is working very well for me. –
Grebe
@curthipster: Thanks. Note that amazon have recently added "object expiration", which renders the code less relevant. See here docs.amazonwebservices.com/AmazonS3/latest/dev/… –
Illa
Great tool. I love command line stuff. +1 from me –
Betts
@MaximVeksler FYI, the export command on the CLASSPATH is not right. It references "target/dependency/commons-logging-1.1.1.jar" but the actual jar in the dependency is version 1.1.3. –
Dunstan
If you use amazon's console and on a one-time basis need to clear out a bucket: You can browse to your bucket then select the top key then scroll to the bottom and then press shift on your keyboard then click on the bottom one. It will select all in between then you can right click and delete.
Not a great idea if you have thousands of files. –
Goldfarb
If you have ruby (and rubygems) installed, install aws-s3 gem with
gem install aws-s3
or
sudo gem install aws-s3
create a file delete_bucket.rb:
require "rubygems" # optional
require "aws/s3"
AWS::S3::Base.establish_connection!(
:access_key_id => 'access_key_id',
:secret_access_key => 'secret_access_key')
AWS::S3::Bucket.delete("bucket_name", :force => true)
and run it:
ruby delete_bucket.rb
Since Bucket#delete returned timeout exceptions a lot for me, I have expanded the script:
require "rubygems" # optional
require "aws/s3"
AWS::S3::Base.establish_connection!(
:access_key_id => 'access_key_id',
:secret_access_key => 'secret_access_key')
while AWS::S3::Bucket.find("bucket_name")
begin
AWS::S3::Bucket.delete("bucket_name", :force => true)
rescue
end
end
I guess the easiest way would be to use S3fm, a free online file manager for Amazon S3. No applications to install, no 3rd party web sites registrations. Runs directly from Amazon S3, secure and convenient.
Just select your bucket and hit delete.
Now available at: s3fm.com –
Concise
Currently doesn't support buckets in the EU though :( –
Poulter
S3Fox and the AWS console don't support deleting all. I was sat there selecting 160 records (I've got about 20,000) for an hour until I got bored and found this question. –
Perusse
One technique that can be used to avoid this problem is putting all objects in a "folder" in the bucket, allowing you to just delete the folder then go along and delete the bucket. Additionally, the s3cmd tool available from http://s3tools.org can be used to delete a bucket with files in it:
s3cmd rb --force s3://bucket-name
I hacked together a script for doing it from Python, it successfully removed my 9000 objects. See this page:
One more shameless plug: I got tired of waiting for individual HTTP delete requests when I had to delete 250,000 items, so I wrote a Ruby script that does it multithreaded and completes in a fraction of the time:
http://github.com/sfeley/s3nuke/
This is one that works much faster in Ruby 1.9 because of the way threads are handled.
This is a hard problem. My solution is at http://stuff.mit.edu/~jik/software/delete-s3-bucket.pl.txt. It describes all of the things I've determined can go wrong in a comment at the top. Here's the current version of the script (if I change it, I'll put a new version at the URL but probably not here).

# Deleting an Amazon S3 bucket is hard.
#
# * You can't delete the bucket unless it is empty.
#
# * There is no API for telling Amazon to empty the bucket, so you have to
# delete all of the objects one by one yourself.
#
# * If you've recently added a lot of large objects to the bucket, then they
# may not all be visible yet on all S3 servers. This means that even after the
# server you're talking to thinks all the objects are all deleted and lets you
# delete the bucket, additional objects can continue to propagate around the S3
# server network. If you then recreate the bucket with the same name, those
# additional objects will magically appear in it!
#
# It is not clear to me whether the bucket delete will eventually propagate to
# all of the S3 servers and cause all the objects in the bucket to go away, but
# I suspect it won't. I also suspect that you may end up continuing to be
# charged for these phantom objects even though the bucket they're in is no
# longer even visible in your S3 account.
#
# * If there's a CR, LF, or CRLF in an object name, then it's sent just that
# way in the XML that gets sent from the S3 server to the client when the
# client asks for a list of objects in the bucket. Unfortunately, the XML
# parser on the client will probably convert it to the local line ending
# character, and if it's different from the character that's actually in the
# object name, you then won't be able to delete it. Ugh! This is a bug in the
# S3 protocol; it should be enclosing the object names in CDATA tags or
# something to protect them from being munged by the XML parser.
#
# Note that this bug even affects the AWS Web Console provided by Amazon!
#
# * If you've got a whole lot of objects and you serialize the delete process,
# it'll take a long, long time to delete them all.

I am one of the Developer Team member of Bucket Explorer Team, We will provide different option to delete Bucket as per the users choice... 1) Quick Delete -This option will delete you data from bucket in chunks of 1000. 2) Permanent Delete-This option will Delete objects in queue.
Amazon recently added a new feature, "Multi-Object Delete", which allows up to 1,000 objects to be deleted at a time with a single API request. This should allow simplification of the process of deleting huge numbers of files from a bucket.
The documentation for the new feature is available here: http://docs.amazonwebservices.com/AmazonS3/latest/dev/DeletingMultipleObjects.html
I've always ended up using their C# API and little scripts to do this. I'm not sure why S3Fox can't do it, but that functionality appears to be broken within it at the moment. I'm sure that many of the other S3 tools can do it as well, though.
Delete all of the objects in the bucket first. Then you can delete the bucket itself.
Apparently, one cannot delete a bucket with objects in it and S3Fox does not do this for you.
I've had other little issues with S3Fox myself, like this, and now use a Java based tool, jets3t which is more forthcoming about error conditions. There must be others, too.
I'll have to have a look at some of these alternative file managers. I've used (and like) BucketExplorer, which you can get from - surprisingly - http://www.bucketexplorer.com/.
It's a 30 day free trial, then (currently) costing US$49.99 per licence (US$49.95 on the purchase cover page).
Try https://s3explorer.appspot.com/ to manage your S3 account.
This is what I use. Just simple ruby code.
case bucket.size
when 0
puts "Nothing left to delete"
when 1..1000
bucket.objects.each do |item|
item.delete
puts "Deleting - #{bucket.size} left"
end
end
Use the amazon web managment console. With Google chrome for speed. Deleted the objects a lot faster than firefox (about 10 times faster). Had 60 000 objects to delete.
