In SCID, go to the file menu, click new, and it will make a new database. Give it a name.
Click on the tools menu, and choose Import Fle of PGN games. {EDIT Sorry, forgot to say it will ask you for a file name, navigate to your PGN file, and import that. It will import all the games into your new database,
