[2020] Friendly PSA - RiotClientServices permanently writing 294GB file on my SDD | Valorant Dev Tracker

So my C drive filled up yesterday - thought to myself "huh that's odd I had so much space?" - deleted 180 gb of games. Went on with my life.

About 10 minutes ago I got the notification I'm full again. "Wtf?" Delete another GB of temp files. Start looking for some sort of culprit. Open task manager to figure out what it could be. Turns out RiotClientServices is writing to my C drive constantly. Like... Constantly. That GB disappeared in about a minute.

"Wtf" Go to see if I can find and delete all the garbage - I just have Valorants folder at ~8gb. Have never played league etc.

Had to delete another 10GB of stuff just to be able to quickly download/install Windirstat (open source free software to visualize hard drives)

Turns out Riot was writing a client log permanently. I don't know how common this bug is. I don't even know what they were attempting to log.

I'm just trying to save someone else from deleting things unnecessarily like I did. If you find yourself running out of hard drive space every day then maybe I have spared you the search for the culprit.

This bug was mentioned and I thought they said they fixed it and you just needed to restart but guess not

It has been fixed, if you look at the name of the offending file it is 2020-04-07. That is the date the issue occurred and also the date we pushed out a fix to the issue.

One thing I would like to note is that the file would have eventually been cleaned up. The way it works is every time you launch the game a new file is created and the oldest one is deleted. It only keeps a certain number of files around. With enough launches this very large file would have become the oldest and been deleted.

While the immediate issue has been fixed, we are following up on making it so a runaway bug can not cause issues like this in future. This was a very serious bug and has caused a lot of discussion on our side in order to prevent it from ever happening.
