These font files are for the vector and raster fonts, as defined. It can be utilized in some support modules of GDI through their smart text generators. However, in particular, the formats in vector are more often utilized by GDI compared to support modules. The file extension FNT is common to both vector and raster font file. This is due to the process both undergo; they begin with common information, and then carry on with the different information for each specific kind of file.

The font files stored with the FNT file extension in the form xxx.fnt are shown in the following: tables, rasterizers and glyphs. In Windows 3.0, the header of the font file with the .fnt file extension is made up of 6 new fields, namely; dfColorPointer, dfBspace, dFlags, dfCspace, dfReserved1 and dfAspace. However, these fields aren't utilized in some Windows versions, and to ensure future versions' compatibility with Windows, they are needed to be particularly configured to zero. This is due to the fact that majority, if not every device driver has support for Windows 2.x fonts, but not all have support for the Windows 3.0 version.

The font files with the FNT file extension of Windows 3.0 include the dfCharTable, which has the structures for describing bits for the characters included in a font file. In this version, fonts can exceed the size more than 64K, which is the Windows 2.x fonts' limit. The utilization of the 32-bit offsets of the dfCharTable's character glyphs makes this possible.

The 32-bit offsets, with their possible large size, cause the fonts to be designed for the utility on the system running in the protected mode of Windows 3.0. It will also need a processor with 80386 or advanced/ higher, where the registration in 32-bit can have access to the character glyphs. In the event that both of the stated conditions are met, the device drivers work properly in the Windows 3.0.
