The configuration setting **Replace invalid NTFS characters** at _[Preferences → General → Filenames](https://community.mp3tag.de/t/preferences-and-configuration/56296#filenames-5)_ might be what you're looking for.

> If enabled, characters that are not allowed in Windows NTFS filenames are automatically replaced by an underscore `_` on field lookup. The following characters are replaced: `\ : / * ? < > | "`.

> Enabling the automatic replacement also prevents folder creation when using the converter **Tag - Filename** with fields that contain the forward slash character `/`.
