How to upload the folder to azure blob storage using java sdk?

Question

Hi,

I have a use-case where I need to upload the folder recursively to Azure Blob. Seems there is no api which takes folder as parameter and uploads all the files recursively.

Currently I am preparing the files list and uploading one by one.

Please suggest is there any utility which provides support to upload the folder .

Thanks in advance.

@BALAJI N Welcome to Microsoft Q&A Forum , Thank you for posting your query here

There is no folder concept in Blob storage ( since it's flat structure).

Java Blob upload sample: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-java?tabs=powershell%2Cenvironment-variable-windows#upload-blobs-to-a-container

If its ADLS Gen 2 storage, then you have the concepts of Directory / folder, The sample code for this is here:

Java sample code upload to folder : https://learn.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-directory-file-acl-java#upload-a-file-to-a-directory

You can convert blob storage to ADLS Gen 2 storage if required.
