All the new additions have a "*" before the application name, for example: *Spyware Doctor, this is the one for Spyware Doctor, so if you want to clean the files on SD that option needs to be checked, if you don' want to clean just uncheck, like you always do when cleaning normally. If you are not sure what is the application X then browse on Google for it, maybe you just don't even need that app anymore, which will free up even more space, lol.
