Hello. This is my favourite preset when converting tags to filenames as this both creates directories for the album, and renames the file to the format I want. This is my preferred template:
%ALBUMARTIST% - %ALBUM% '['%YEAR%']'/$num(%track%,2). %artist% - %title%
This works flawlessly in windows as windows simply omits the "/" which sometimes occurs in 2 and 3 track EP's. My problem now is, I've recently switched to macOS, and I want to use the same format. While this template works mostly flawlessly, there's the odd 2 and 3 track EP with "/" in the album field. What mp3tag for macOS does instead is it cuts up the name of the album, creating several sub-directories, depending on how many "/" are in the album name. It's a minor inconvenience with those albums and I hope this gets resolved soon.

MP3Tag uses slashes in format strings for filenaming to create subfolders. You use this feature yourself in your format string.
If a tagfield contains a slash your have to replace it woth another character for the filename.
It is not a good idea anyway to use the slash in the filenames of MacOs for interoperability.
You have to replace slashes with another character, e.g
%ALBUMARTIST% - **$replace(%ALBUM%,/,)**'['%YEAR%']'/$num(%track%,2). %artist% - %title%
In my example the slash is replaced with nothing.
Have a look at the help for the scripting funktion $replace().

Please also see [Preferences → General → Filenames](https://community.mp3tag.de/t/preferences-and-configuration/56296#filenames-5) where you can **Replace invalid NTFS characters** on field lookup.
> Enabling the automatic replacement also prevents folder creation when using the converter **Tag - Filename** with fields that contain the forward slash character `/`.
