How to clear favorite servers in Killing Floor

A guide for a regular player. Nothing complicated: close the game, make a backup, clear the list, open the game and check.

What gets deleted

Only the servers in the Favorites list are deleted.

These are not touched:

• characters;
• perks;
• graphics settings;
• maps;
• mods;
• saved game files.

The easiest way

Works if Killing Floor is installed here:

D:\games\SteamLibrary\steamapps\common\KillingFloor

1. Close Killing Floor.
2. Press Win + X.
3. Choose Terminal or Windows PowerShell.
4. Copy the whole command below.
5. Paste it into the PowerShell window.
6. Press Enter.

$ini = 'D:\games\SteamLibrary\steamapps\common\KillingFloor\System\KillingFloor.ini'
$backup = "$ini.bak-favorites-$(Get-Date -Format yyyyMMdd-HHmmss)"
Copy-Item -LiteralPath $ini -Destination $backup

$encoding = [Text.Encoding]::GetEncoding(28591)
$text = $encoding.GetString([IO.File]::ReadAllBytes($ini))
$text = [regex]::Replace($text, '(?ms)^Favorites=.*?(?=^Favorites=|^\[|\z)', '')
[IO.File]::WriteAllBytes($ini, $encoding.GetBytes($text))

"Done. Backup: $backup"

After that open Killing Floor and check:

Multiplayer -> Server Browser -> Favorites

The list should be empty.

Example

Before:

Favorites=(ServerID=0,IP="80.96.59.223",Port=7707,...)
Favorites=(ServerID=0,IP="46.4.12.165",Port=7707,...)
Favorites=(ServerID=0,IP="185.97.253.250",Port=7707,...)

After:

SteamLoginMenuClass=ROInterface.ROSteamLoginPage

[XGame.xDeathMatch]

That is fine: there are no Favorites=... lines between those lines anymore.

If you want to do it manually

1. Close Killing Floor.
2. Open the file:

D:\games\SteamLibrary\steamapps\common\KillingFloor\System\KillingFloor.ini

3. Find the line:

SteamLoginMenuClass=ROInterface.ROSteamLoginPage

4. Below it, delete every line that starts with:

Favorites=

5. Stop before the line:

[XGame.xDeathMatch]

6. Save the file.

Important: some server names look strange and can span several lines. So for the manual way use Notepad++ or another editor that shows line numbers. If you are not sure, use the PowerShell command from the section above.

If the list came back

Sometimes Steam keeps its own separate list of favorite servers. It is shared by the old Steam Server Browser, not only by Killing Floor.

Do this only if the list came back after clearing KillingFloor.ini.

1. Close Steam completely.
2. Find the Steam icon in the bottom right corner of Windows.
3. Right-click it.
4. Choose Exit Steam.
5. Open PowerShell.
6. Paste the command:

$steamUserData = 'C:\Program Files (x86)\Steam\userdata'
$stamp = Get-Date -Format yyyyMMdd-HHmmss
$emptyFavorites = "`"Filters`"`r`n{`r`n`t`"favorites`"`r`n`t{`r`n`t}`r`n}`r`n"

Get-ChildItem -LiteralPath $steamUserData -Directory | ForEach-Object {
    $vdf = Join-Path $_.FullName '7\remote\serverbrowser_hist.vdf'
    if (Test-Path -LiteralPath $vdf) {
        Copy-Item -LiteralPath $vdf -Destination "$vdf.bak-favorites-$stamp"
        [IO.File]::WriteAllText($vdf, $emptyFavorites, [Text.Encoding]::ASCII)
        "Cleared: $vdf"
    }
}

After that start Steam and Killing Floor.

How to undo everything

If something went wrong, the backup sits next to the original file.

For the main Killing Floor file the backup looks roughly like this:

D:\games\SteamLibrary\steamapps\common\KillingFloor\System\KillingFloor.ini.bak-favorites-20260719-153000

To restore it:

1. Close Killing Floor.
2. Delete the current file:

D:\games\SteamLibrary\steamapps\common\KillingFloor\System\KillingFloor.ini

3. Rename the .bak-favorites-... file back to:

KillingFloor.ini
