delete everything in /tmp; you're not really using it anyways and you'll get more disk space. lol
i literally used this same logic when i merged the contents of c:\windows & c:\win32 because there were so many duplicate files and folders and i needed to recover the free space.
sometimes i'm thankful for my cluelessness; examples like this paint me into corners and this particular corner was the impetus behind my exploration into linux; which has sustained my career for the last 25ish years through several once-in-a-lifetime economic recessions and multiple personal setbacks.
linux is the best mistake i've ever made.
