What is FLI?

FLI and FLC are taken for different names of one format. In fact those files that have extension .fli are of older format. The new format was not limited to 320x200 resolution and had better compression. The files of the new format got the extension .flc. There is also FLX files which are a slight variation on the standard FLC format.

As both names become widespread and refer to the same variations of the same format we use FLI/FLC when describing the formats.

FLI/FLC format appeared in 1993 as an animation format (developed by Autodesk, Inc). FlI/FLC format is widely used for scientific cartoon type movies (animated graphs, etc.). FLI/FLC movies are more deairable than MPEG as 640x480 movies can be played back at reasonable speeds on X11 workstations, PCs and Mac.
