How Do I Clear My Storage?

I was trying to import more sprites onto my latest game and found that I was somehow already out of storage. I have only made a few games so far, none of which are particularly large games or use any music. I believe that the problem is the size of my sprites, which to be fair I have made rather massive in order to get more detailed visuals, but I want to be sure that this is the case before resizing my files because I do enjoy the higher-quality visuals. Is there any other way to clear my storage? Is there anything other than my large sprite assets that may be taking up my storage space?

Nevermind, I realised how absurdly and unnecessarily large my assets were. Tip to anyone else experiencing my problem: Check how small you can compress your sprites without affecting the visual. Chances are if you made them as big as I did, you can half the size and STILL retain the detail you are hoping for.

If you need a lot of space you can run MicroStudio locally - just install Node.js and download the MicroStudio source code from github.
