CKEditor How to remove image files in server when canceled posts

I'm using nodeJS(back-end), react(front-end), mongoDB. And I installed CKEditor5 for posting on board with many images.
It perfectly works uploading images on my server folder with CKfinder. But If someone stop to post with images uploaded, useless images remain on my server folder. And, delete uploaded images on the editor (like tab a delete key), still remain on server folder.
How can I delete images on my server folder when users delete images on editor or stop to post with images uploaded.

File upload and download - Angular with Node

I am working on project where I have to store a file/img/pdf for a particular user instance and retrieve the files when the user logged in.
So the theme is, whenever user uploads a file it should be populated in his screen like profile pictures, invoice PDF's etc.,
Moreover, I just want to perform a carousel slideshow of uploaded images by user.
I came through several baked in modules such as ng-file-upload in angular and I was successful in uploading files too but how can I retrieve the particular file from the server and display them to user?
What is the best practice to achieve this?
Thanks in advance!
