Connect and share knowledge within a single location that is structured and easy to search. I have a bucket in s3 called "sample-data". Inside the Bucket I have folders labelled "A" to "Z".
Inside each alphabetical folder there are more files and folders. What is the fastest way to download the alphabetical folder and all it's content? In the above example the bucket sample-data contains an folder called a which contains foo. I know how to download a single file. For instance if i wanted foo. However i am wondering if i can download the folder called a and all it's contents entirely? Any help would be appreciated.
You list all the objects in the folder you want to download. Then iterate file by file and download it. The response is of type dict. Use the below script to download a single file from S3 using Boto3 Resource. Create necessary sub directories to avoid file replacements if there are one or more files existing in different sub buckets. Then download the file actually.
You cannot download folder from S3 using Boto3 using a clean implementation. Instead you can download all files from a directory using the previous section. Its the clean implementation. Refer the tutorial to learn How to Run Python File in terminal. And then we include the two files from the excluded files. Let us say we have three files in our bucket, file1, file2, and file3. And then with the help of include, we can include the files which we want to download. Example - --include "file1" will include the file1.
To download the entire bucket, use the below command -. The above command downloads all the files from the bucket you specified in the local folder. As you may have noticed, we have used sync or cp in the above commands. Just for your knowledge, the difference between the sync and cp is that the sync option syncs your bucket with the local folder whereas the cp command copies the objects you specified to the local folder.
For our purpose to download files from s3 we can use either one of sync or cp. I believe this post helped you solve your problem.

Take a look at the picture, you see the word "FAIL". 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.
Since it performs operations between two directories, it can be implemented when wanting to upload or download contents.
