Answer 1

idea.properties file contains the default limits for the files IntelliJ IDEA can handle:

#---------------------------------------------------------------------
# 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.
#---------------------------------------------------------------------
idea.max.intellisense.filesize=2500

#---------------------------------------------------------------------
# Maximum file size (kilobytes) IDE is able to open.
#---------------------------------------------------------------------
idea.max.content.load.filesize=20000

These can be changed using Help | Edit Custom Properties.
