COMO: Ignorar a Lixeira ao excluir arquivos e pastas no Windows XP
Permanently Bypass the Recycle Bin
You can permanently bypass the Recycle Bin by changing the configuration of the Recycle Bin:
- Right-click the Recycle Bin, and then click Properties.
- In the Recycle Bin Properties dialog box,
click to select the Do not move files to the Recycle Bin.- Remove files immediately when deleted check box.
- Click OK.
You can also configure Windows XP to skip the confirmation message whether or not you are using the Recycle Bin. In the Recycle Bin Properties dialog box, click to clear the Display delete confirmation dialog check box, and then click OK.
ps: Eu mudei de XP algum tempo atrás; não posso confirmar isso. Observe que um bypass permanente pode ser perigoso.
Diga-me se funciona para você.
