How to delete an empty folder?

[jezaman]

Hello,

I have a setup where inside my bucket, i organise files based on project
So files are stored as {projectUUID}/{filename}

How do i delete the actual empty folder?
I found that i can use deleteFiles to delete the files inside the folder
await bucket.deleteFiles({
prefix: ${project}/,
});

But this doesn't delete the folder. I tried doing a manual delete of the folder path afterwards but that doesn't seem to work.
I tried removing the trailing '/' but that didn't have an effect either.

I really think this repo could use some basic examples. There is so many super complex examples already there, but there is not a basic example of "Delete multiple files" or a "Delete a folder".

And yes i know technically there are no folders inside the bucket.

Hello @jezaman, it sounds like you are referring to simulated folders. If so, there is nothing in particular you need to do to delete the folder because it doesn't actually exist. See the docs here

Yes i know that, but the empty non-existent folder does remain in my Google Cloud Storage overview in Google Cloud Console. I was expecting that if all the files would be removed, the path would also be removed from the Console.

@jezaman I would try performing a getFiles() to see if the folder / files still exist. It might be some weirdness with the console. I can also check if having a softDeletePolicy has any impact.

Hello @jezaman , i encountering an issue with the deleteFolder method from the @google-cloud/storage-control library, with Hierarchical namespace enabled. When I try to delete a folder, I encounter the error: "The folder you tried to delete is not empty." Below is the code snippet I am using:

async deleteFolder() {
    const res = await this.controlClient.deleteFolder({
      name: `projects/_/buckets/${this.bucketName}/folders/Content/test/`,
    });
    return "Delete folder successfully";
}

Could you please provide some guidance on whether this method is designed exclusively for empty folders, or if there is a recommended approach for handling non-empty folders? Any assistance would be greatly appreciated.
Thank you for your support.
