When I open an eps file (made in another application) in Illustrator I get a message telling me that fonts were missing and had to be replaced. Obviously this is not correct cause I can easily change the font manually into the intended font once I'm past that message. So how do I solve this problem? It's so tedious to have to change all the text manually after opening it! Where are the font files stored anyway? Does it use the fonts that are in the Windows folder?
