See below for batch file code snippet to use with SDelete. Add to your “User/Administrator/AppData/Roaming/Microsoft/Windows/SendTo” (In Vista/7/Serv08) or “Documents and Settings\%username%\SendTo” (In XP).
(%APPDATA% environment variable actually points to “C:\users\\AppData\Roaming”)
I have modified the code below from it’s original source on blog (see references) to 3 passes instead of four. See wikipedia page for more information on data remanence. If the script runs slow on your system consider decreasing this to 3 or 4.
if "%~f1"=="" (
echo No more args given. Done.
exit /b 0
ECHO Y| cacls %1 /T /C /G Administrators:F
attrib -h -s -r -a %1 /S /D
attrib -h -s -r -a %1\*.* /S /D
sdelete -p 7 -s -q %1
Windows 7 environment path seems to be buggy at times. Absolute references to executables is more reliable.
@echo off :START if "%~f1"=="" ( echo No more args given. Done. exit /b 0 ) :WORK ECHO Y| C:\Windows\System32\cacls.exe %1 /T /C /G Administrators:F C:\Windows\System32\attrib.exe -h -s -r -a %1 /S /D C:\Windows\System32\attrib.exe -h -s -r -a %1\*.* /S /D C:\Windows\System32\sdelete.exe -p 7 -s -q %1 :NEXTARG shift goto START
Any snippets may have been condensed from their original sources for brevity. See references for original articles.
