How to rename files and folder in Amazon S3?

Question

Is there any function to rename files and folders in Amazon S3? Any relevant suggestions are also welcome.

Answer 1

There is no direct method for renaming a file in s3. what you need to do is copy the existing file with a new name (just set the target key) and delete the old one.

Answer 2

I just experienced this and it works:

aws s3 --recursive mv s3://<bucketname>/<folder_name_from> s3://<bucket>/<folder_name_to> 

Answer 3

You can use AWS console commands for mv files

Answer 4

I just did it. You can use the AWS SDK for PHP as follows:

 use Aws\S3\S3Client; $sourceBucket = '*** Your Source Bucket Name ***'; $sourceKeyname = '*** Your Source Object Key ***'; $targetBucket = '*** Your Target Bucket Name ***'; $targetKeyname = '*** Your Target Key Name ***'; // Instantiate the client. $s3 = S3Client::factory(); // Copy an object. $s3->copyObject(array( 'Bucket' => $targetBucket, 'Key' => $targetKeyname, 'CopySource' => "{$sourceBucket}/{$sourceKeyname}", )); 

http://docs.aws.amazon.com/AmazonS3/latest/dev/CopyingObjectUsingPHP.html

Answer 5

 aws s3 cp s3://source_folder/ s3://destination_folder/ --recursive aws s3 rm s3://source_folder --recursive 

Answer 6

You can use the AWS CLI or s3cmd command to rename files and folders in the AWS S3 bucket.

Using S3cmd, use the following syntax to rename a folder,

 s3cmd --recursive mv s3://<s3_bucketname>/<old_foldername>/ s3://<s3_bucketname>/<new_folder_name> 

Using the AWS CLI, use the following syntax to rename a folder,

 aws s3 --recursive mv s3://<s3_bucketname>/<old_foldername>/ s3://<s3_bucketname>/<new_folder_name> 

Answer 7

It is not possible to rename a folder through a graphical interface, the fastest (and easiest if you like the GUI) way to achieve this is to run a plain old copy. To do this: create a new folder on S3 using the graphical interface, go to your old folder, select everything, check "copy" and then go to the new folder and select "paste". After that, delete the old folder.

This simple method is very fast, because it is a copy from S3 for itself (there is no need to re-download or something like that), and it also supports the permissions and metadata of the copied objects, as you expected.

Answer 8

This works to rename a file in the same folder.

 aws s3 mv s3://bucketname/folder_name1/test_original.csv s3://bucket/folder_name1/test_renamed.csv 

Answer 9

Here's how you do it in .NET using the S3.NET SDK :

 var client = new Amazon.S3.AmazonS3Client(_credentials, _config); client.CopyObject(oldBucketName, oldfilepath, newBucketName, newFilePath); client.DeleteObject(oldBucketName, oldfilepath); 

PS try to use "asynchronous" versions of client methods where possible, although I did not do this for readability

Answer 10

Now it is possible for Files, select the file, then select More> Rename in the GUI.

To rename a folder, you instead need to create a new folder, select the contents of the old one and copy / paste it (again under "More")

Answer 11

The file and folder are actually objects in S3. You must use PUT OBJECT COPY to rename them. See http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html

Answer 12

As Naaz replied, direct renaming of s3 is not possible.

I added a code snippet that will copy all the content

only works add your passkey and secret key

here is what i did in the code

-> copy the contents of the source folder (sub-child and folders) and paste into the destination folder

-> when copying is complete, delete the original folder

 package com.bighalf.doc.amazon; import java.io.ByteArrayInputStream; import java.io.InputStream; import java.util.List; import com.amazonaws.auth.AWSCredentials; import com.amazonaws.auth.BasicAWSCredentials; import com.amazonaws.services.s3.AmazonS3; import com.amazonaws.services.s3.AmazonS3Client; import com.amazonaws.services.s3.model.CopyObjectRequest; import com.amazonaws.services.s3.model.ObjectMetadata; import com.amazonaws.services.s3.model.PutObjectRequest; import com.amazonaws.services.s3.model.S3ObjectSummary; public class Test { public static boolean renameAwsFolder(String bucketName,String keyName,String newName) { boolean result = false; try { AmazonS3 s3client = getAmazonS3ClientObject(); List<S3ObjectSummary> fileList = s3client.listObjects(bucketName, keyName).getObjectSummaries(); //some meta data to create empty folders start ObjectMetadata metadata = new ObjectMetadata(); metadata.setContentLength(0); InputStream emptyContent = new ByteArrayInputStream(new byte[0]); //some meta data to create empty folders end //final location is the locaiton where the child folder contents of the existing folder should go String finalLocation = keyName.substring(0,keyName.lastIndexOf('/')+1)+newName; for (S3ObjectSummary file : fileList) { String key = file.getKey(); //updating child folder location with the newlocation String destinationKeyName = key.replace(keyName,finalLocation); if(key.charAt(key.length()-1)=='/'){ //if name ends with suffix (/) means its a folders PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, destinationKeyName, emptyContent, metadata); s3client.putObject(putObjectRequest); }else{ //if name doesnot ends with suffix (/) means its a file CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName, file.getKey(), bucketName, destinationKeyName); s3client.copyObject(copyObjRequest); } } boolean isFodlerDeleted = deleteFolderFromAws(bucketName, keyName); return isFodlerDeleted; } catch (Exception e) { e.printStackTrace(); } return result; } public static boolean deleteFolderFromAws(String bucketName, String keyName) { boolean result = false; try { AmazonS3 s3client = getAmazonS3ClientObject(); //deleting folder children List<S3ObjectSummary> fileList = s3client.listObjects(bucketName, keyName).getObjectSummaries(); for (S3ObjectSummary file : fileList) { s3client.deleteObject(bucketName, file.getKey()); } //deleting actual passed folder s3client.deleteObject(bucketName, keyName); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } public static void main(String[] args) { intializeAmazonObjects(); boolean result = renameAwsFolder(bucketName, keyName, newName); System.out.println(result); } private static AWSCredentials credentials = null; private static AmazonS3 amazonS3Client = null; private static final String ACCESS_KEY = ""; private static final String SECRET_ACCESS_KEY = ""; private static final String bucketName = ""; private static final String keyName = ""; //renaming folder c to x from key name private static final String newName = ""; public static void intializeAmazonObjects() { credentials = new BasicAWSCredentials(ACCESS_KEY, SECRET_ACCESS_KEY); amazonS3Client = new AmazonS3Client(credentials); } public static AmazonS3 getAmazonS3ClientObject() { return amazonS3Client; } 

}

Answer 13

S3DirectoryInfo has a MoveTo method that will move one directory to another directory, so that the moving directory will be a subdirectory of another directory with the same name as it originally was.

The extension method below will move one directory to another, that is, the moved directory will become another directory. In fact, it creates a new directory, moves the entire contents of the old directory into it, and then deletes the old one.

 public static class S3DirectoryInfoExtensions { public static S3DirectoryInfo Move(this S3DirectoryInfo fromDir, S3DirectoryInfo toDir) { if (toDir.Exists) throw new ArgumentException("Destination for Rename operation already exists", "toDir"); toDir.Create(); foreach (var d in fromDir.EnumerateDirectories()) d.MoveTo(toDir); foreach (var f in fromDir.EnumerateFiles()) f.MoveTo(toDir); fromDir.Delete(); return toDir; } } 

Answer 14

There is one software where you can play with an s3 bucket to perform various kinds of operations.

Software Name: S3 Browser

S3 Browser is a free Windows client for Amazon S3 and Amazon CloudFront. Amazon S3 provides a simple web services interface that you can use to store and retrieve any amount of data at any time from anywhere on the network. Amazon CloudFront is a content delivery network (CDN). It can be used to deliver your files using a global network of peripheral locations.

---

If this is only once, then you can use the command line to perform these operations:

(1) Rename the folder in the same bucket:

 s3cmd --access_key={access_key} --secret_key={secret_key} mv s3://bucket/folder1/* s3://bucket/folder2/ 

(2) rename bucket:

 s3cmd --access_key={access_key} --secret_key={secret_key} mv s3://bucket1/folder/* s3://bucket2/folder/ 

Where to,

{access_key} = Your valid access key for s3 client

{secret_key} = Your valid scratch key for client s3

It works fine without any problems.

rename all * .csv.err files in the <<bucket>>/landing directory to * .csv files using s3cmd

  export aws_profile='foo-bar-aws-profile' while read -rf ; do tgt_fle=$(echo $f|perl -ne 's/^(.*).csv.err/$1.csv/g;print'); \ echo s3cmd -c ~/.aws/s3cmd/$aws_profile.s3cfg mv $f $tgt_fle; \ done < <(s3cmd -r -c ~/.aws/s3cmd/$aws_profile.s3cfg ls --acl-public --guess-mime-type \ s3://$bucket | grep -i landing | grep csv.err | cut -d" " -f5)
