File Extension: .esm, .esp

A Data File acts as a database of all of the data for the world, including object data, dialogue, gameplay settings, object placements, AI settings, landscape, cells, etc. There are two types of data file Master Files .esm and Plugin Files .esp which are the core data files of Fallout.

Files

Master files and plugins are largely identical in format, but have some important distinctions in practice.

Master: .esm

  • A master file is autonomous; it relies on no information other than itself.
    • The Creation Kit will not create master files.

Plugin: .esp

  • A plugin ESP file relies on information from a master ESM file.
    • Plugins can only refer directly to data from a master file (though they can refer to multiple master files).
    • Plugins can only refer to information in another plug-in indirectly by using scripts.
    • Plugins can be masterless if they only add new content.

Tooling

  • The Creation Kit is the primary tooling for working with data files.
  • There are community software projects that provided tooling for working with data files.

Notes

  • By tradition, the file extensions stand for Elder Scrolls Master and Elder Scrolls Plugin.
