Step 2: The "Game Mode" – Add Exclusions to Windows Security

If verification finished without error, your security software is the likely culprit. Here is the better approach—don't disable protection; create exceptions.

For Windows Defender (Built-in):

1. Go to Windows Security > Virus & threat protection.
2. Click Manage settings (under Virus & threat protection settings).
3. Scroll to Exclusions > Add or remove exclusions.
4. Click Add an exclusion > Folder.
5. Navigate to your game installation folder (e.g., C:\Program Files (x86)\Steam\steamapps\common\Rise of the Tomb Raider).
6. Add the folder. Also add your Steam Library folder if it is in a different location.

For Third-Party Anti-Virus (Avast, McAfee, etc.):

• Open the AV dashboard > Settings > Exceptions/Exclusions.
• Add the full path to Rise of the Tomb Raider folder.
• Critical: Also add the BigFile.000 file specifically as an exception.

The "Better" Twist: Restart your PC after adding exclusions. Many AVs cache blocks until a full reboot. rise of the tomb raider bigfile000 error better
