EspConvert
DESCRIPTION:
EspConvert is a fast experimental converter for Bethesda plugin files.
Currently supported:
- ESP/ESM → XML export
- Streaming architecture for very large files
- Partial support for multiple Bethesda engine generations
Current performance:
- Starfield.esm: creates a 2 GB XML file in 95 seconds
- Oblivion: 22 s for an XML of 352 MB
- Fallout 3: 17 s for 412 MB XML
- Fallout 4, Fallout New Vegas and Morrowind do not work yet
Why this project exists:
- Opening even small Starfield plugins in Creation Kit can take several minutes
- Export e.g. Starfield.esm once and keep a searchable XML version forever
- Better understanding of Bethesda content
- Enable future tooling outside Creation Kit/xEdit
EspConvert focuses on:
- Speed
- Extremely low memory usage (Starfield.esm is converted using less than 16 MB RAM)
- Stream processing - write data without storing it
Project Status: preview/some esp features still missing
This is an application that can also be fetched from https://sourceforge.net/projects/esp-convert/. It has been hosted in OnWorks in order to be run online in an easiest way from one of our free Operative Systems.
