[RMMV] 413 REQUEST ENTITY TOO LARGE ERROR

Hello. I'm currently having an error when trying to upload a download file to this site. Whenever I attempt to upload "Meteo Chronicles BETA 0.5" about 60% though uploading the site crashes and it displays the error "413 Request Entity Too Large." Is my game's file size too large? It's only about 490,000 KB. Is that too much for this site to handle? Any help would be appreciated. Thanks.

Edit: What the frick. I just did a bit more searching, and my game is literally over 9.3 GB uncompressed! That's bigger than Zelda Breath of the Wild! How the hecky did my game's files get that large? It's not even complete yet!

Edit 2: Does anyone have any tips for lowering the file size? I have literally no clue how it got this large. I only have about 35 OGG songs, the basic RTP, and some custom battlers... How the heck did my game this large? I don't understand.

Edit 3: Nevermind. The large file size was just a glitch with my computer. The REAL file size is about 350 MB. Nothing to worry about.

Ok, got it. My actual game files are exactly 424 MB, with the compressed, zipped version which is the one I'm actually uploading being 319 MB. Which one does it count? The actual file size or the file size of the compressed file? The compressed file is the one I'm actually uploading but the actual files is what people will need to have to play my game, (IE they must uncompress the ZIP file into a regular folder to play) so which one is counted? Thanks.

P.S.: Maybe the error was caused with there not being enough RAM currently available on my PC since I was exporting a video file from my video-editing software which was taking up the majority of my RAM?
