What is the .hl3 extension used in? --Nicksaysmeep 14:03, 24 January 2014 (PST)

I have a .hl3 in my Portal 2 files right now. Also, what exactly are the differences between all these save formats? Pinsplash (talk) 21:00, 13 July 2018 (UTC)

.hl1 = all the main save data and current entities
.hl2 = adjacent map list / adjacent clientstate
.hl3 = (removed entities; that will be restored)
