What “reviewed” means on this page
- Format fit: whether the “what is this file?” description plausibly matches common real-world use of the extension, including category, typical MIME types, and aliases.
- Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps. Not every step was tested on every OS version.
- Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
- Sources and further reading: external links should point to vendors, standards bodies, or other primary references where possible; not every detail is individually sourced.
- Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless. Pages without “Reviewed by” have not been through this editorial pass yet.

What is a .FLI file?
.FLI is a file extension for a video format developed by Autodesk for animation sequences. It is often used in older animation software and is recognized by its efficient compression for simple animations.
Background
The .FLI file format was developed by Autodesk for use in their animation software, specifically for storing animation sequences. It was popular in the late 1980s and early 1990s as a format for simple animations due to its efficient compression techniques. Although not as commonly used today, it remains a part of many legacy systems and archives. FLI files are typically associated with Autodesk Animator, a program that was widely used for creating animations during its time. They are known for their simplicity and small file size, which made them suitable for the hardware limitations of the era. Despite being largely replaced by more modern formats, .FLI files can still be opened and converted using specialized software, ensuring that historical animations are preserved.
