Game Saves & Odd Files in "Steam\userdata\"

[Hidden_Gamer_87]

Hey everyone,

So i know steam saves some games files to this folder "Steam\userdata\" but when i look in there i have 18 different folders. 17 of them have there names as a long set of numbers and the other is called Unknown.

I share my pc with another person and we both use steam and have our own accounts. Im assuming one of these folders will be related to my profile and have my save games (yes i know not all save games will be kept in here)

So my question is, how can i tell which one of those folders is my folder? as id like to backup my saves (i dont use could i had issues with it before so turned it off)

My next question is what are all these folders? there are 18 of them, assuming 2 of them are used for my account & another is used for the other user of my pc that leaves 16 other random folders.

Also 15 out of the 18 folders, all have the same single folder in them called "ugcmsgcache" and in those are a single file with a long name with a ".cachedmsg" extension.

In the folder "Unknow" is another 8 folders all named with long numbers. They each again have one folder in them called "inventorymsgcache" and each of those are 2 files with a long name and again the extension is ".cachedmsg"

What is this? is that normal? is it safe to delete them?

This number is ID3. You can convert it to your profile ID or back.
https://steamid.io/
(Enter it in this format: U:1:that number)
Or enter your profile link and you will see your ID3.

ED: Inside ID3 folders there are folders for each game with Game ID as names.
ED2: That second person could create or use ~17 Steam accounts :) You can find them all with the help of that site.
ED3: all your screenshots are stored in userdata (jpg).

I dont know about Unknown folder and what it can be.

Thank you, using that i have found the one that belongs to me. I also asked the other user and they only have 1 steam account and we looked his up as well and found the folder for his.

So we still have 16 unknow folders, and using the link you provided using the folder name to try search for its account they all come back as profiles like this

So im not really sure what to do with all the other folders.

Steam creates folder in userdata only after logging in corresponding account.
Steam/config/loginusers.vdf - this is a text file with logins of all accounts used on your computer (after the last steam or system reinstal).

It uses non-standard end of line characters. But WordPad or your internet browser should read it without problems. I use Lister from Total Commander.

What to do with those folders. I think you can delete them if they don't have some important personal data like screenshots or saves. Don't confuse them with 2 "real" folders.

Why do they exist. In fact i don't know. Maybe somebody were experimenting with creating steam accounts... The only possible problem i can think of is you PC is compromised. You can check it for viruses just in case.

Look at the creation date of that folder. If it matches the account creation date, then long ago someone created an account on your computer.
