LSOs are Flash cookies, so...aren't they cleaned by the Flash cleaning already ?
I only see the option to delete cookies.
I use this via a batch file on my WinXP system and it zaps the junk very fast, it covers physical files but I don't know if there's any Flash super cookie junk in the registry since I've never looked for it in there.
@echo echo Removes Adobe Flash Player cache, super cookies, and other junk del /q /s /f "%USERPROFILE%\APPLICATION DATA\ADOBE\FLASH PLAYER\*.*" rmdir /q /s "%USERPROFILE%\APPLICATION DATA\ADOBE\FLASH PLAYER\ASSETCACHE" del /q /s /f "%USERPROFILE%\APPLICATION DATA\MACROMEDIA\FLASH PLAYER\*.*" rmdir /q /s "%USERPROFILE%\APPLICATION DATA\MACROMEDIA\FLASH PLAYER\#SHAREDOBJECTS" cls exit
To delete Flash Cookies, you need to have the "Adobe Flash Player" box checked in the "Applications\Multimedia" section.
