What is a .FLI_ file extension?

.FLI_ file extension is created by Autodesk, Inc.. .FLI_ has been classified as Digital video and movie Files.

.FLI_ is Autodesk Animator FLIC animation old format

This is the format developed by AutoDesk that is designed for storing brief animations.

FLI is limited to images 320 by 200 pixels and allows a palette of 256 colors (although the palette can be changed from line to line to give more colors per frame).

FLI is based on a fixed frame rate specified in "ticks per frame" (there are 70 ticks per second), and has an implicit 6:5 aspect ratio. In theory, all FLI animations must loop, but in practice this requirement is often ignored. The image data in FLI files is compressed using a Run-length compression scheme.

This is suitable for animations, but is inappropriate for videos or dithered images. The FLI format has largely been superseded by its close cousin, (but more flexible) FLC format.

The fli_ file extension was used on old versions of Mac OS.

.FLI_ file format is deprecated and this file format is no longer supported.

Currently, .FLI_ file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.
