I downloaded Pencil2d, but when I open the program, it just shows the files for it. What do I need to open it properly?
@isitdeltarune Hi. Pencil2D is basically a portable application, so yes, the files you extracted are indeed what makes the software run. after that you simply need to double click the “pencil2d.exe” file which is the only one that has a little icon with the logo.
However if after doing that you get any other sort of error, please take a screenshot of it and reply back with the screenshot so we can help you further 
Thank you! It works now! Have a great day~
@isitdeltarune Glad to hear it, you too have a great day!
