If none of the above works:

The "unable to open bigfile.000!" error in Rise of the Tomb Raider
typically indicates file corruption or a failure of the game engine to access its critical archive data. While verifying game files through Steam is the standard fix, users often report that the error persists even after verification says files are "verified". Why Verification Often Fails
The core issue is often that Steam's verification tool confirms the file's presence and size but may miss subtle "Tiger Archive header mismatches" or internal corruption within the massive .tiger files. Additionally, system-level conflicts—such as antivirus blocks or RAM instability—can prevent the game from reading these files even if they are technically correct. Verified Solutions for the Bigfile.000 Error
To resolve this issue when standard verification fails, follow these steps: 1. Force a Re-download of the Specific File
Steam may ignore the file if it thinks it is already there. You must manually force a refresh:
Navigate to your game installation folder (usually Steam\steamapps\common\Rise of the Tomb Raider). Locate and delete or rename bigfile.000.tiger.
Open Steam, right-click the game, select Properties > Installed Files, and click Verify Integrity of Game Files. rise of the tomb raider bigfile000 error verified
Steam will now recognize the file is missing and download a fresh, clean copy. 2. Security Software Exclusions
Aggressive antivirus software can "lock" these large files during startup, leading to an access error.
Add the entire Rise of the Tomb Raider folder as an exclusion in Windows Defender or your third-party antivirus. Ensure the game's .exe is set to Run as Administrator. 3. Compatibility and Display Settings
Sometimes the error is triggered by the game's inability to initialize the display before accessing files.
The bigfile000.tiger error in Rise of the Tomb Raider is a frustrating file-read issue that typically indicates data corruption or a mismatch between the game and its archives. While standard verification often fails to find the culprit, specific "verified" community workarounds consistently resolve the crash. Verified Fixes for the Bigfile Error
If you are encountering this error, these methods are the most effective ways to restore stability:
The "Clean Validation" Method: Sometimes Steam fails to detect the corruption if the file is still present. Go to your game installation folder (usually Steam/steamapps/common/Rise of the Tomb Raider) and manually delete all bigfile.000.tiger through bigfile.011.tiger files. After deleting them, go to Steam, right-click the game → Properties → Local Files → Verify Integrity of Game Files to force a fresh, clean download of these core archives.

DirectX 12 Toggle: Many users found that switching the API fixed immediate "disc error" crashes during gameplay. If you can reach the launcher, enable DirectX 12 in the options menu.
Driver Rollback: While it sounds counterintuitive, some recent driver updates conflict with the older TressFX or physics engine in the game. Users have reported success by rolling back NVIDIA or AMD drivers to a version roughly three months old.
Antivirus Exceptions: Third-party antivirus programs often flag the large .tiger archives as suspicious, blocking the game from reading them. Add an exception for the entire Rise of the Tomb Raider folder in your security software. Why This Happens
This error is often a case of "bitrot" or an interrupted update that leaves the archive headers mismatched. Because these bigfiles contain the bulk of the game's assets, any single corrupted block will cause a "Failed to open" or "Disc error" crash the moment the game tries to load that specific asset.
