# 010 Editor (ARCHIVED)
We can now use Wolvenkit's [File Editor](https://app.gitbook.com/s/-MP_ozZVx2gRZUPXkd4r/wolvenkit-app/editor/file-editor "mention"), and hex editing has become obsolete. As of April 2026, you shouldn't have to use a hex editor – ever.
If you find that you have to do this anyway, please create a [ticket on github](https://github.com/WolvenKit/WolvenKit/issues) so that we can tech this away..
