An FGC file is a greeting card file created by Greeting Card Factory, a program used to customize and send greeting cards. It contains a greeting card project, which includes the text, graphics, effects, layout information that appear in the card.

When you create a card in Greeting Card Factory and save your progress, the program creates the FGC file to store its contents. You can reopen the file after closing it in order to resume your progress. Everything that appears in your card is saved in the FGC file. Greeting Card Factory comes with a large amount of pre-designed cards to choose from that can be given for birthdays, holidays, anniversaries, graduations, and other special occasions. It also provides many different graphics you can add to cards, effects you can apply to text, and a photo editor.
