ChessDB is a free chess database application developed by Dr. David Kirkby. Its .epd files store chess positions in a database intended for use by the ChessDB application.
The file belongs to ChessDB's position-database data and is not a general chess game document.
Open an .epd file with ChessDB on Microsoft Windows. ChessDB is the known application for working with this particular chess format and provides access to the stored chess positions.
A general text editor may display the file contents, but it will not provide ChessDB's database features.
No established conversion utility is known for ChessDB .epd files. They are position-database files intended to be used by ChessDB.
If the positions are needed in another format, use an export option provided by ChessDB or by the target chess application, if supported.
