How to delete files in multiple unknown folders from a single bat file?

Question

Suppose I don't know names of all the folders in a directory. I want to delete all the .exe file in those folders from a single bat file. What will be the command? Is it possible?

cd ?
del *.exe 

Solution 1

Try to do

del /s *.exe

/S stands for delete from all Subfolders (DELTREE)

Solution 2

Using FOR to iterate over directories:

for /d %i in (*.*) do del %i\*.exe
