Article 4(1)(4) of the Personal Data Protection Act provides that "personal data file system" refers to an assembly of personal data arranged in a structured set  and can be retrieved by certain criteria, regardless of the ways in which the database is set up, stored or organized. "File system" may be broadly interpreted as a file, which may include folders or a set of folders. If the file contains personal data, then processing the file would fit in the applicable scope of the Act.
