Notes about the EPD file extension:



Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The EPD file type is primarily associated with 'ChessDB' by Dr. David Kirkby. ChessDB is a database program used for storing chess games. A ChessDB format database consists of three files: .SI3 (index file); .SN3 (name file); .SG3 (game file) (those 3 are needed to make one database). These are all binary files. Some complete databases are held on the ChessDB web site. At the time of writing, one database (called 'huge') has over 3.5 million games. Other files used in ChessDB are: .PGN (Portable game notation, which is used in lots of chess programs, so is not unique to ChessDB); .EPD (Extended Position Description); .SSO (Search options file); .SOR (Repertoire file); .DAT (used on four files - engines.dat history.dat options.dat and recent.dat) to hold configuration information. All are text files.
