Long file path support

Wolvenkit showed me a popup, how do I fix this?

What are long filepaths, and why do I need them?

This should be a standard setting in every operating system. Unfortunately, Windows doesn't care.

In the year of our lord 2025, Windows does not (by default) support file paths longer than 256 characters — and if you're somebody who likes to use subfolders, this will break Wolvenkit's mod packing.

We decided to show you a warning at every startup, because

• the fix is super easy

• we can't solve the problem in Wolvenkit

• if you run into this, you'll be unable to create mods

How to enable long filepath support?

Windows

If you don't trust something you read on a random modding wiki, find the full guide at microsoft.com.

1. Open a Powershell window as administrator (Keyboard shortcuts: Windows+R, type powershell, pressCtrl+Shift+Enter) Correct Powershell (shows Administrator in the title bar): Incorrect Powershell (doesn't show Administrator in the title bar ⇒ runs as user):

2. Paste the following command:

New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem" `
-Name "LongPathsEnabled" -Value 1 -PropertyType DWORD -Force

1. Press Enter

That's it! You now have long path support enabled.

Linux

This feature is supported out-of-the-box. Just try to stay under 4000 characters.
