FEA files use Adobe's feature-file syntax to describe OpenType Layout features, such as ligatures, substitutions, positioning rules and language-specific behavior. They are source data rather than finished font files.
Adobe Font Development Kit, FontLab Studio and FontForge can use a fea file as part of the font-building process. The software interprets the feature definitions and compiles them into the OpenType tables of a TrueType-flavored or CFF-based OpenType font, usually saved with a .ttf or .otf extension.
Adobe Font Development Kit is available for Microsoft Windows, while FontLab Studio and FontForge are available on multiple platforms.
A fea file is a text file, so it can be viewed in any text editor. To use or edit its OpenType feature definitions, open it in Adobe Font Development Kit, FontLab Studio or FontForge on a supported platform.
A fea file is source data and is not normally converted to another text format. Adobe Font Development Kit, FontLab Studio or FontForge can compile its definitions into the OpenType tables of an exported .ttf or .otf font.

Record marked as obsolete and not updated for a long time.
FilZip is a data-compression tool for Microsoft Windows. The fea file extension is used for data associated with the application.
The exact contents depend on how FilZip created or used the file. It is a supporting FilZip data file rather than a generally supported interchange format.
FilZip seems to be an obsolete product.
Open the fea file with FilZip on Microsoft Windows. Because FilZip is obsolete, it may not be available or may not work correctly on current Windows versions.
There is no established general-purpose converter for FilZip data files. If the file can still be read by FilZip, use any export or save options provided by that application.
If FilZip cannot open the file, it may not be possible to convert it without the original software.
