Putting files inside their own folders guarantees that files with the same name can be added without any problems.
To override this default folder structure, a class that conforms to the PathGenerator-interface can be specified as the path_generator in the config file.
Let's take a look at the interface:
* Get the path for the given media, relative to the root storage path.
*/publicfunctiongetPath(Media $media): string;
* Get the path for conversions of the given media, relative to the root storage path.
*/publicfunctiongetPathForConversions(Media $media): string;
* Get the path for responsive images of the given media, relative to the root storage path.
*/publicfunctiongetPathForResponsiveImages(Media $media): string;
There aren't any restrictions on how the directories can be named. When a Media-object gets deleted the package will delete its entire associated directory. To avoid tears or worse, make sure that every media gets stored its own unique directory.
