Yes, you can export selected PST folders into EML format instead of the whole files. Recently I found a tool that allowed selective conversion. The GainTools PST to EML Converter gave me the option to choose specific folders before exporting. That made the process much more convenient. I selected only the required emails and saved them in EML format. The output files were organized properly and easy to access. It is much easier than exporting everything manually.
