I'm trying to rotoscope

I’m just trying to create an animation for a song but I can’t do that if the only files showing are folders, more specifically 2048 game files

When rotoscoping, the typical process is to import a video to a dedicated layer with the “File > Import > Movie Video” option. This supports basically all the common video formats. Files for all supported video formats will be displayed in your file explorer window. If the file you want to import isn’t showing up, you’re using the wrong import option or the file does not have the file extension of a supported file type.

If this does not help you enough to solve your issue, you’re going to need to provide more information. What file type are you trying to import? How are you importing it? What operating system are you on? Which version of Pencil2D are you using?
