Take too much to delete too many files folder in window explorer.

Using following simple steps to delete files using command prompt with less time

use rmdir to delete the files and subfolder,

rmdir /s/q MyFolderPath
However, it is significantly faster, especially when you have a lot of subfolders in your structure to use del before the rmdir, like this:

del /f/s/q MyFolderPath > nul
rmdir /s/q MyFolderPath
