1.
mp3 are not very small files!
File Size: 500 B to 19 KB
2. 5000 files (this is not - much) as compared to
310,000 files
!

3. You delete 1 folder or 1000000 or more different subfolders and how many partitions and how many multiple HDD?
Next time, please check it out and stop writing nonsense that it works fast!

Very small files (1 B .. 1 MB etc.) Slowest copying and deleting
---------------
Small (e.g. MP3), medium and large files (faster copying, and deleting)
It worked much faster than the deleting process in Explorer.
I do not use Windows Explorer to find and delete files.
Everything I rarely use because it is very slow scans disks!
I use a different, more rapid file search tool (uses only RAM, Without building base)
Everything - a good tool for previewing files (Large Thumbnail)
