There is only one file type that uses the .VFB extension:
FontLab Studio Font File
Font file created by FontLab Studio, a font authoring program; contains a designed font, which includes the glyphs that make up the alphabet and other symbols; stores the font in a vector format so that the glyphs can be scaled without losing quality.
When done editing fonts in FontLab Studio, you can export them to .TTF, .OTF, .PFB, and .PFA formats. Selectfrom the application menu.
VFB files can be opened by several FontLab products, including FontLab Studio, Fontographer, TypeTool, AsiaFont Studio, TransType Pro, and others.
