An OTF file is a font file saved in the OpenType format developed by Adobe and Microsoft. It combines aspects of the PostScript and TrueType font formats. OTF fonts are fully scalable, meaning the characters can be resized without losing quality.
Standard font format used by Mac OS X; font contents are stored in the data fork part of the file instead of the resource fork (which was used by fonts in Mac OS Classic).
