“Delete Folder Content”, mai pe romaneste, deletes the contents of a folder. It's a registry hack which will add this option in Windows Context Menu (the menu that appears when you right-click on a folder). See the image below:

This option will appear in the Windows Context Menu if you make a small registry change.
open Notepad.exe and copy/paste the code below:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\shell\Delete Folder Contents]
[HKEY_CLASSES_ROOT\Directory\shell\Delete Folder Contents\command]
@="cmd /c \"cd /d %1 && del /s /q *.*"
Save the file on the Desktop with the extension .reg (delete.reg, for example), then double-click it. Click "Yes" & “Ok”.
When you right-click on a folder whose content you want to delete, you will notice that the "Delete Folder Content" option has appeared.
I don't know if this hack is valid on Windows XP, but on Windows Vista and Windows 7 it definitely works (tested).
