Delete all files while maintaining directory structure

Question

Given the directory structure c:\a\b\c\d\ - what DOS command will delete all files contained in c:\a along with any files in the subdirectories b, c, and d? We do not want to delete any directories - just files.

Answer 1

DEL /S C:\a

You need to use RMDIR to remove directories.

Answer 2

Use:

del *.* /s /q

Check the directories are still there:
