The ArchiveInvalidation.txt File Generator is a utility for manually generating the ArchiveInvalidation.txt file, primarily for use with hi-res texture mods. This version will work for Oblivion, Fallout 3, and Fallout New Vegas.

There's no doubt that many users have already found work arounds for getting custom textures to work correctly, however this is intended for those who wish to manually generate this file.

For myself, with Fallout New Vegas, I have not found a satisfactory alternative yet (Fallout New Vegas ArchiveInvalidation Invalidated hasn't been updated in years), and have been manually maintaining this file instead. So far, despite being a manual process, this approach has worked perfectly for me.


The tool scans for all dds files that are located under the games Data folder:


and then builds the list of files:


My hope is that others may also find it useful as well.

My Favorite Hi-Res Mods:


Just unzip the download file anywhere you like, then run the ArchiveInvalidation.exe file.

None really. Simply delete the ArchiveInvalidation.exe file.

1) Select which Game you wish to set the invalidation settings for.If the game is installed, the paths should now be automatically detected:
  • Game Path[C]:Program Files (x86)Steamsteamappscommonfallout new vegasFalloutNV.exe
  • Game INI Path[C]:Users[your profile]DocumentsMy GamesFalloutNVFallout.ini
2) Click the "Enable Invalidation" button to turn on invalidation. OR Click the "Disable Invalidation" button to turn off invalidation.

Advanced Section (Optional):
  • Click the "Find Files" button to search for any custom/mod textures and meshes.
  • Click the "Setup" button to display the Setup Window, which is used to manually configure the Game Name List.
  • Click the "Debug Info" button to display the Debug Window (mainly for troubleshooting purposes).
  • Click the "View In Notepad" button to show the entire list of files detected by using the Find Files button click.
  • Click the "Compare" button to determine if there any recent file additions that need to be included in the archive file.


Important Notes:
Please keep in mind that as you change (add/remove) your texture mods, you must rerun the "Enable Invalidation" option again to refresh the ArchiveInvalidation.txt file. Doing this will ensure that the file is updated with the latest files you have.

If you encounter any problems though, please let me know by posting the issue on the Nexus Site, and I'll get it fixed asap.
