+		[b]Note:[/b] Accessing project ("res://") directories once exported may behave unexpectedly as some files are converted to engine-specific formats and their original source files may not be present in the expected PCK package. Because of this, to access resources in an exported project, it is recommended to use [ResourceLoader] instead of [FileAccess].

In practice, this means that since imported resources are stored in a top-level [code].godot/[/code] folder, only paths to [code].gd[/code] and [code].import[/code] files are returned (plus a few other files, such as [code]project.godot[/code] or [code]project.binary[/code] and the project icon). In an exported project, the list of returned files will also vary depending on [member ProjectSettings.editor/export/convert_text_resources_to_binary].
