Installed into System's Font folder. .TTC TrueType Collections Windows also supports TrueType Collections, or ".TTC" files, which contain several 'sfnt' font structures organized with a simple directory scheme. This organization allows the individual fonts to share complete tables among each other. These fonts have also not historically been usable on the Macintosh until MacOS 8.5. .OTF OpenType Font OpenType fonts represent a new naming and packaging for fonts. Adobe, in conjunction with Microsoft, have defined a data-fork-based, 'sfnt' structured font file to contain PostScript font data. The glyph data itself is stored in a new format called CFF, or Compact Font Format. The notion behind this structure is that these fonts could behave the same as TrueType fonts on Windows and Macintosh platforms.
