What's in the Steam client log files?

I am trying to get my account verified on a discord server (The Forbidden Trove) and they asked me to send them my log files. Just want to make sure that I'm only sending them information that I'm fine with sharing.

Hopefully someone can point me to the information if it's available.

Apologies if I was vague. I just want to know how the log files work. Whether I send them has nothing to do with GGG.

I'm gonna outline the general tidbits the tools community knows about the client log file as it's often used in tools to do trade companions and such:

It's a human-readable text file you can read in a text editor.
It contains past conversations between you and people you've chatted with in-game, as long as neither of you are in a region that requires that text to not be stored.
It contains information about guild membership and also the minutiae about which zones you've entered when and which game instance servers those areas have been on, as well as the gateway servers you've connected to.
There is no information about your own IP address, your account details or similar personal information.
It also may occasionally contain some diagnostic information about your GPU, your sound devices, stuff like that.
The contents vary over time as GGG logs whatever they feel relevant to log to make it easier for them to support end users after things happen.
And no, "[STARTUP] Tencent Start" doesn't mean anything fishy ;)

Edit: It does log the path to the cache/download/settings folders. Those may be in your user profile directory and as such contain your computer username.

There are several magic numbers that can seem suspicious in it, breaking down a typical log line here for your understanding:

"

2023/10/22 16:39:58 402128296 f22b6988 [INFO Client 23500] Tile hash: 3713433821

The parts are:
* "2023/10/22 16:39:58" - the current time on your computer;
* "402128296" - the time in milliseconds since the OS was started;
* "f22b6988" - a value only meaningful to GGG, it's about where in the program the message came from, varies between game builds as code may move around;
* "[INFO Client 23500]" - message severity, game system and process ID;
* "Tile hash: 3713433821" - message specific data, here a hash value of what the terrain generator generated (used to ensure that the server and client did the same work).

Thank you very much. This is exactly what I needed to know.

Oh, I forgot one thing - it does log the path to the cache/download/settings folders. Those may be in your user profile directory and as such contain your computer username.
