I noticed this when I deleted a 2 GB video file on my laptop today, which took less than 5 seconds. But when I deleted a separate folder that was smaller than 2 GB, it took way longer to get deleted.

Imagine your computer’s storage like a book, with the data being the writing and the files being the chapters.
When you erase a file, you’re not actually blanking the pages, you’re just removing the chapter from the index.
That’s why a single 2GB file deletes faster than a folder with two hundred 10MB files. Although both cases have 2GB of data, there’s one index entry in one case and two hundred index entries in the other.
