I think it may be cleaning needed files, others I don’t see why it is cleaning them out:

C:\Program Files (x86)\Steam\steamapps\common\GoatSimulator\GoatGame\Localization\INT\|ChatDialog.txt- I believe this file is used for the text that NPCs have in the game.

C:\Program Files (x86)\Steam\SteamApps\common\Call of Duty World at War\Docs\ There are readme files here that help with issues in running the game.

PIA VPN- Has issues connecting unless TAP driver is re-installed. Perhaps have a notice box with this?

Terraria- gets rid of .bak backup world files, which may be needed if a world’s data corrupts.

C:\Program Files (x86)\Steam\steamapps\common\PAYDAY 2\mods\downloads\|downloads.txt

C:\Program Files (x86)\Steam\steamapps\common\PAYDAY 2\mods\Enhanced Hitmarkers\|changelog.txt

C:\Program Files (x86)\Steam\steamapps\common\PAYDAY 2\mods\Music Control\|changelog.txt

C:\Program Files (x86)\Steam\SteamApps\Common\Star Wars BattleFront II\|Update1_1.txt

C:\Program Files (x86)\Steam\steamapps\common\Terraria\|changelog.txt

C:\Program Files (x86)\Steam\steamapps\common\Crayon Physics Deluxe\|changelog.txt

These are all changelogs mainly, I don’t see why they get deleted. I find them useful. The downloads.txt explains to users the purpose of the folder for that mod.

I don’t know which of these are intended to be deleted or not, but I thought I’d just bring it to the dev’s attention.
