Maybe I posted this in the wrong place originally So I'm posting it here ... I've been reading a lot about people questioning this and can't seem to find a solid answeR. I have a huge chunk of miscellaneous files taking up space on my Samsung Galaxy tab but I'm not sure if they are Safe to delete. Is there an app in Google play store that will safely delete what is not needed by the system and apps to run properly? I use Avast cleanup and Empty Folder Cleaner but neither takes care of miscellaneous files.
