The patch.dat / patch.fat files contain post-release updates, DLC, and multiplayer fixes.
Many mods (like Ziggy's Mod, Redemption, or FC3 Realism) replace these files. To revert to original/vanilla:
Why has the number "72" become a colloquialism for these files? In the community, it is often associated with the file size (often roughly 72MB in compressed form for the primary patch payload) or an internal versioning header visible only via a hex editor.
This versioning hints at a development mystery. Within the patch.fat header of the launch version, internal timestamps coincide with the "Gold" status date of late 2012. Later patches (v1.01, v1.02) replaced these files, expanding the .dat and .fat sizes. The "72" files are unique because they represent the game before the "Day One Patch" era fully took hold—a time when the disc contained the intended experience, rather than a stub for a mandatory download.
This creates a bifurcation in the Far Cry experience:
The keyword emphasizes the word "original" for a critical reason: Once you install a mod, your patch.dat and patch.fat are permanently altered. You cannot simply "uninstall" a mod by deleting it; the game needs the original Ubisoft files to verify integrity.
Common scenarios requiring the original v72 files:
Without the original v72 patch.dat and patch.fat, any new mod installation is like building a house on a cracked foundation.
This happens to thousands of players. You download a mod, drag-and-drop a new patch.dat into your Far Cry 3 directory, overwriting the original. Six months later, you want to try a new mod, but the old mod’s files are incompatible.
If you do not have a backup of the original v72 files, here is your recovery path:
To give you a more precise answer:
What exactly is “72” referring to?
This report analyzes the specific data files mentioned, which are primarily associated with game modding and maintaining compatibility with popular fan-made overhauls. 1. Identifying the Files: patch.dat and patch.fat Far cry 3 original patch.dat patch.fat 72
, the patch.dat and patch.fat files are located in the data_win32 folder of your game installation.
Purpose: These are "BigFile" archives that contain the game's core gameplay values, such as weapon damage, ammo capacity, health settings, and AI behavior.
The Pair: You must always have both files together. The .fat (File Allocation Table) acts as a directory index, while the .dat contains the actual compressed data.
Modding Role: Most "old-style" mods are distributed as pre-modified patch.dat/fat pairs. To install a mod, users typically back up their original files and overwrite them with the modded versions. 2. The Significance of "72"
While patch file sizes vary by game version, the specific reference to "72" most likely refers to the Far Cry Patch v1.3 for the original Far Cry (2004), which has a file size of 70.83 MB (often rounded to 71 or 72 MB in discussions).
In the context of Far Cry 3, a file size around 72 MB might refer to:
A "Lite" Mod: Some smaller gameplay tweaks or "Fix" mods (like a mouse acceleration fix) result in a patch.dat file of roughly this size.
Version 1.05/1.06 Differences: In 2018, Ubisoft released an update (v1.06) that changed the common.dat/fat and patch.dat/fat files, breaking many older mods like Ziggy’s Mod. Modding guides often recommend "original" or "downgraded" v1.05 files to restore compatibility. 3. Usage & Compatibility How to install mods? - Far Cry 3

The patch.dat and patch.fat files in Far Cry 3 are essential archive files that contain the game's updated assets, values, and scripts. If you are looking for a guide to restore or modify these files, follow the steps below based on your needs. Locating the Files
The default location for these files depends on your installation: Path:
Standard Install: C:\Program Files (x86)\Ubisoft\Far Cry 3\data_win32. Restoring Original Files
If your files are corrupted or you wish to remove mods, you can restore the originals using these methods:
Verify Integrity: Right-click the game in your Steam Library (Properties > Local Files > Verify Integrity of Game Files) or Ubisoft Connect (Manage > Verify Files). This will automatically redownload the original patch.dat and patch.fat files. Steam (if applicable):
Manual Backup: It is highly recommended to create a backup of your original patch.dat and patch.fat files before applying any mods. Modifying the Patch Files
If you are trying to "unpack" these files to edit game values (like health or damage), you must use third-party tools:
Download Mod Tools: Use tools like the Gibbed Dunia 2 toolset.
Unpack: Drag the patch.fat file onto Gibbed.Dunia2.Unpack.exe. This creates a folder named patch_unpack containing the individual game files. Edit: Modify the XML files within the unpacked folder.
Repack: Drag the patch_unpack folder back onto Gibbed.Dunia2.Pack.exe to generate a new patch.dat and patch.fat. Version Compatibility (Patch 1.05 vs 1.06)
Some older mods specifically require files from v1.05 because the v1.06 update (released years later) changed the way certain files are handled. If a mod crashes your game, you may need to use a v1.05 restoration guide to replace your patch.dat/fat with the older versions.

Title: The Digital Archaeology of the Rook Islands: Deconstructing the "72" Build in Far Cry 3
Abstract
In the landscape of modern gaming preservation, few artifacts are as enigmatic as the unmodified launch files of classic titles. This paper explores the technical and historical significance of the Far Cry 3 file set identified by the community as "patch.dat / patch.fat 72." By examining the Dunia Engine 2 architecture, the role of these container files, and the specific versioning associated with the "72" nomenclature, we uncover a snapshot of Ubisoft’s open-world philosophy during the twilight of the seventh console generation. This analysis serves as a case study for the importance of version control and the hidden complexities of game data archiving.
If you have spent more than a few hours modding Far Cry 3, you have likely encountered a specific, almost ritualistic set of files: patch.dat and patch.fat. Among the modding community—especially on forums like Nexus Mods, Mod DB, and Reddit’s r/farcry—you will see a recurring, enigmatic phrase: “Make sure you start with the Far Cry 3 original patch.dat / patch.fat (version 72).”
For the uninitiated, this sounds like obscure tech jargon. For the seasoned modder, it is the golden rule. This article will explain exactly what these files are, what the "72" version signifies, why the "original" state is sacred, and how to properly restore these files to troubleshoot or switch mods.
If your internet is slow and verification takes hours, some modding communities host the original patch.dat/fat v72 as a direct download. Disclaimer: Ensure you trust the source, as these are large executable-adjacent files. Look for uploads from known users on Nexus Mods or Mod DB. The file size should be exactly 1,843,232 KB for patch.dat (v72) and approximately 14,500 KB for patch.fat.
