What changed

Version 2 made a number of changes to the way Quick Configuration works.

The following goes into detail over the changes if you're curious.

Table of Contents

Mod manager

Resource list overwritten

In v1, the contents of the resource list was saved to a resources.txt file in the Mods folder. When running the app, it overwrote the resource list if it was manually edited in Fallout76Custom.ini.

v2 tries to rectify this by treating the resource list in the Fallout76Custom.ini (or Project76Custom.ini depending on the profile) as the "ground truth". It will always load the resource list from there, so your manual changes should not be overwritten anymore.

Configuration files overwritten

In v1, all files from the mod folder were copied and overwritten on each deployment. This included configuration files for mods. This let to user's mod configuration getting overwritten by the mod manager.

To mitigate this, v2 copies configuration files only once. If a configuration file (ending with *.ini, *.json, *.xml, etc.) is found in the game's folder or "Data" folder, it will no longer be overwritten. This should preserve your configuration.

Installation options

If you've used the v1 before, you might remember that it came with different installation options, such as:

  • "Bundle into *.ba2 archives with other mods"
  • "Create separate *.ba2 archive"
  • "Copy loose files"

These options were removed in v2. There is only a single "installation option" going forward and it's mostly equivalent to the old "Copy loose files". Except that it actually adds *.ba2 archives to the selected resource list automatically (defaults to sResourceArchive2List).

That means, if a mod comes with "loose" files that need to be added to one or more ba2 archives, you need to create them manually. The mod manager guide will have a section explaining that in detail.

Also, the "frozen" archives are removed as well. Just copy *.ba2 files into the mod's folder directly.

Multiple *.ba2 archives for a single mod

It's now possible to manage multiple *.ba2 archives for a single mod. They will automatically be added to the resource list.

Bundled archives

In v1, bundled archives were archives that bundled resources from multiple mods into individual archives such as Bundled.ba2, Bundled - Textures.ba2, etc.

In v2, this option was deliberately removed. As it stands, the mod manager was breaking mods this way. Usually, mod authors already create ba2 archives for you. So the mod manager makes no attempt at changing them anymore.

You can still use the algorithm from v1 to package your own bundles from "loose" files if you desire, but you'll have to do so manually. There's a button under "Archive2" in the mod manager's tool row. See Archive2 for more info.

Drag and drop requires a window now

Dragging and dropping files into the mod manager requires you to open a separate window. This is explained in detail in the Troubleshooting article.

*.ini files and tweaks

Backups

v1 created a "Backups" folder next to the ini files automatically. This was done originally so users could restore their ini files in case the app overwrote something they needed.

In v2, this was removed because it let to a ton of duplicated files and storage was wasted. If you find a configuration that well works for you, please create your own backups of the ini files.

Custom tweaks

The custom tweaks view was removed. Please use a code editor to edit the ini files directly. You can open them through the app: "Explore" → "Fallout76.ini" (etc.)

Also, the extra files it added (e.g. Fallout76Prefs.add.ini) are no longer merged in. You can delete them safely.

Note that the app needs to be restarted after making changes to the ini files directly to make sure that the app loads the changes. The app doesn't watch for external changes while it runs.

I recommend using Visual Studio Code to edit the ini files, but you can also open them in any program you want (Windows Notepad, Notepad++, etc.).

Gallery

The gallery exists in v2, but it's half-baked at the moment. It only supports viewing screenshots / photos from a couple predefined folders such as the game's installation directory, the game's photos folder and the Steam screenshots folder. Other features from v1 have not been reimplemented yet.

Configuration files

v2 reuses the same directory structure and paths that v1 used. However, instead of xml and ini, it primarily uses json files now:

  • config.ini -> config.json
  • profiles.xml -> profiles.json

The log files (archive2.log.txt, modmanager.log.txt, update.log.txt) are replaced by just an app-wide log file: Fallout 76 Quick Configuration.log

The only thing that is still reused are the *.xml files in the nexusmods folder and the thumbnails.

Translations

In v2, translations are now saved as *.json files. If you're interested in translating, see: Translations

Old Windows versions

v2 dropped support of Windows 7 and it will no longer run on it. Windows 10 isn't tested, but it may run on it. Please upgrade to Windows 11 or stick with v1 of Quick Configuration.

Alternatively, if you PC does not support Windows 11: Fallout 76 runs well on Linux using Proton and Quick Configuration now runs on Linux natively.
