Prerequisites

If all checks are not passed then the request will be closed.

• I have checked that no other similar feature request already exists.
• I have checked that this feature does not already exist.
• The feature request makes sense for the project.

Proposal

Describe the feature that should be added.

Change adapter so it runs on all files.

for(final File file : Objects.requireNonNullElse(parentFile.listFiles(), new File[0])){
-    if(fileName.equals(file.isDirectory() ? file.getName() : adapter.getName(file))) // use adapter name only if not a directory
+    if(fileName.equals(adapter.getName(file))
        return file;

Reasoning

Explain why this feature should be added.

Developers may want to use adapter names against directories , specifically for checking within them (see https://github.com/Ktt-Development/webdir/pull/79).

If this change is made existing developers can simply use (below) to replicate the previous behavior.

@Override
public final String getName(final File file){
    return file.isDirectory() ? file.getName() : super.getName(file);
}
