how i delete files of Particular extension without recovery in win 7

Hello, Sir,

i need a software or method that i want to delete all file of extension .xlsm from my entire hard drive with out recovery of that files

.thanx

At the command prompt, the following command will do

Code:

DEL /S C:\*.xlsm

Thanx Alejandro85

if i use this command line to delete .xlsm extension. is it unrecoverable by recovery softwares.

No, it will only perform a normal deletion filtering by a particular extension. Nothing can 100% prevent undeletion to be true.

You need to do a "secure deletion" or a "free space wipe" to prevent it for the most part. CCleaner includes an option to do this, which you should run after deleting files the normal way. That should prevent recovery by most normal programs.

Ok thanx alot
