First, a quick understanding of the files themselves. For Tomb Raider (2013), Rise of the Tomb Raider , and Shadow of the Tomb Raider , developer Crystal Dynamics packages nearly all game assets—graphics, models, textures, sounds, and more—into several massive archive files. The primary archive is named bigfile.000.tiger , followed by others like bigfile.001.tiger , bigfile.002.tiger , and so on. Each of these files is typically around 2GB in size.
Always if your PC has 8GB, 16GB, or even 32GB of RAM.
For standard repacks, however, the troubleshooting guide below will resolve the majority of both generic and "header mismatch" errors. bigfile000tiger tomb raider error repack

The instability around .TIGER files in repacks isn't usually a one-off bug; it's a consequence of the file format's complexity and a few common triggers:
: Real-time protection often flags the unpacking process as suspicious, leading it to "quarantine" or delete parts of the bigfile000.tiger archive during installation. Each of these files is typically around 2GB in size
Before re-downloading, check if your installer came with a .bat or .exe file designed to "Verify Integrity" or "Check Files" within the repack folder. Run the integrity check tool.
Repackers use extreme compression algorithms (e.g., FreeArc, ZStd, LZMA2) to shrink a 30GB game to 12GB. During decompression, a single flipped bit in bigfile000.tiger renders the entire archive unreadable. Because this file is the largest (often 8GB+), it is the most likely to corrupt.
