Delete unnecessary files from the client folder

[Valcars]

Hello everyone as the title suggests in my client folder there are so many files that I don't see in other ragnarok servers ... I was wondering if it was possible to delete the files that are not needed to lighten the client ... and which ones can I delete ??? Thanks in advance
