在IntelliJ 2016及更高版本中,您可以从“帮助”菜单的“编辑自定义属性”(如@eggplantbr注释)更改此设置。
在较旧的版本上,没有GUI可以执行此操作。但是,如果您编辑IntelliJ IDEA平台属性文件,则可以更改它:

# Maximum file size (kilobytes) IDE should provide code assistance for.
# The larger file is the slower its editor works and higher overall system memory requirements are
# if code assistance is enabled. Remove this property or set to very large number if you need
# code assistance for any files available regardless their size.
