  • The folder structure is organized in sites and jobs.

  • All files belonging to a specific job - including GFD4 - are stored in a dedicated folder named after the job.

  • Site1.site

    • Job1.job

      • Job1.gfd4

      • Job1.raw

    • Job2.job

      • Job2.gfd4

      • Job2.raw

  • The site folder also includes specific folders for imported and exported data, external references and code lists.

  • Site1.site

    • _Export

    • _Import

    • _ExternalReference

    • _Codes

In old site structure, all job files are directly within the site folder. Site created with latest software version have instead the new structure.
