What is a UFO file?
Raster image primarily created by Ulead PhotoImpact (now Corel PhotoImpact), but also recognized by other photo and video editing applications developed by Ulead; may include multiple editing layers, similar to a Photoshop (.PSD) document.
UFO files can be opened by Ulead Photo Explorer, but multi-layer images may not appear correctly.
NOTE: Ulead was acquired by Corel. While PhotoImpact is still supported, the Photo Explorer software is no longer supported.
File Type 2Unified Font Object File
.UFO File Association 2
A UFO file is a file saved in the Unified Font Object (UFO) format. It contains data about a font, which includes the format version, creator, glyph layers, kerning information, images, and metadata.
You can create UFO files to store a font using Glyphs or RoboFont, which are font editors for macOS. You can also open and edit UFO files using Glyphs and RoboFont in macOS, or FontForge, which is available for Windows, macOS, and Linux.
The first version of the UFO format was originally published in 2004 but is rarely used anymore. The second version was published in 2009 and is the most common version used. The third version was published in 2012 but is not as widely adopted as the second version. The format was developed and is maintained by Tal Leming, Justin van Rossum, and Erik van Blokland.
