"Title says it all pretty much. If you have been playing LoL since beta (As I have) you've probably accumulated a lot of game/abode air logs. I just deleted about 500MB worth of logs.
Most of these are pretty small at about 50KB. Some are up to 1.2MB each.
Each time you log on you get a Abode Air Log and each game you play adds 2 more log files to the bunch. So over the X number of games you've played, the logs can added up to a lot of space taken up.
These files are mostly used to help solve issues with your LoL game or client. If you're having no issues you should go ahead and delete them.
-------Places to find the logs---------
C
Riot Games\League of Legends\game
C
Riot Games\League of Legends\air\logs
Files are named like
"2010-01-17_09-34-46_netlog.txt"
"2010-01-17_09-34-46_r3dlog.txt"
"LolClient.20100203.174554.log"
-----------------------------------------
You can also delete "LOL.AirRuntime_#" (Found in your C
Riot Games\League of Legends) folders. They're made after new Adobe Air patches come out. All they contain are the updated .exe patch which become worthless after they are installed. Normally each .exe is about 15mb.
So do yourself a favor and delete the log files. "
