Playlist Error Caused by APE?

[Rasmussen]

Basically, for the same reason that a macOS application is actually a directory hierarchy -- to keep things neat and orderly and to know where to look for certain files.

For instance (more or less at random), the album JS Bach: Les Quatre Ouvertures by Jordi Savall (Alia Vox AVSA 9890) is organized as follows.

A top level directory "Bach - Quatre Ouvertures". This directory contains the audio files; the "folder.jpg" file; and another directory "cd_info". In its turn, the "cd_info" directory contains directories for CUE sheets, ripping logs, JPG files, PDF files, and XML files, one for each, respectively. (The XML files is where I store tags.) If this were an album of cantatas, then there'd be additional directories for the original German texts and translations. So, for this one double CD album, I have 7 directories.

When I set up my music library, I did consider the issue of nesting and of path length; that's why, as a rule, I don't go deeper than 3 levels and I keep directory names as short as possible; but I never thought that the number of directories itself might be an issue.
