If I want to download all the contents of a directory on S3 to my local PC, which command should I use cp or sync? The aws s3 sync command will, by default, copy a whole directory. For the s3 option, there is also a --dryrun option now to show you what will happen:.
In case you need to use another profile, especially cross account. Make sure you input valid access and secret keys, which you received when you created the account. If you have possible matches in the destination path, I would suggest sync as one LIST request on the destination path will save you many unnecessary PUT requests - meaning cheaper and possibly faster.

Conclusion I believe this post helped you solve your problem. Thank you and keep learning. Let's make a deal Deal. Want to gain more knowledge for free? This can be arranged by using the CLI. The cp command will copy contents of your S3 bucket to another bucket or to a local directory of your choosing.
The end result will be all the contents downloaded to your specified destination. The sync command will recursively copy all the contents in the source bucket to the local destination by default, whereas with the cp command, you have to specify it manually for each request.. This is a great way to begin managing your Amazon S3 buckets and object stores. Due to its construct, S3 is an object store service that has the ability to store single objects up to 5tb in size, for a very low cost.
It is entirely pay as you go and you only pay for what you need, implicating the ability to store massive amounts of data for cheap. Regarding zip files, there is no need to upload files to S3 as such because of its cost effective storage. In other words, S3 stores static assets in a very cost effective way. Users often use it as their primary way of performing operations against their Amazon S3 buckets and objects. This can be accomplished with a variety of commands — the cp and sync commands.
The cp command is very simple to understand. It is basically a way for a user to copy their contents in one directory from another. It is flexible, and can be performed between two Amazon S3 buckets, or between a local directory and an Amazon S3 Bucket.
The following is a C code using linq but it shouldn't be hard to translate to Java. As other have already said, everything in S3 is an object. You will not lose "nested files" there no files, so you will not lose objects whose names are prefixed with the key you delete. Please note that I'm using ProfileCredentialsProvider so that my requests are not anonymous.
Otherwise, you will not be able to delete an object. S3 does not have directories, while you can list files in a pseudo directory manner like you demonstrated, there is no directory "file" per-se.

Michael-sqlbot I didn't create any empty folder. Infact all files are uploaded by the application using the folder structure I reported as prefix for the file key. Such an object would likely be invisible in the console. Here is the code: codeflex.
