Just so you know, we don't know the file format for every file. If it's just a bunch of random characters, it's probably a .zip or .jar.

#   important:
#       ! when using this, make sure this file is loaded as early as possible
#       ! example:
#           - place the file in a folder called "Skript/plugins/_library/"
#           - prefix the file with "_", like "_jNBT.sk"
#           - this will make the file load before others, because Skript loads files alphabetically
