There should be an api for deleting folders

I use this for my cloud storage and currently have a problem when deleting files.
I operate in this way, for example, if there is an activity, I put the activity under the bucket of "activity" with the activity id. The main image of the activity is directly placed in the folder named after the activity id and renamed as "activity". I want to group their images, for example, all other images are under "images", but currently it's very annoying when deleting them. I have to search through all files, but if it's possible to delete a folder. I can just delete the folder named after the activity id.
