An AVF file has no single standardized definition because developers can adopt the extension for any purpose, so one AVF might be readable text, another unreadable binary, and another a known format disguised under the extension, while Windows may wrongly choose an opener based on associations; many AVFs act as behind-the-scenes helper files storing metadata, search indexes, cached visual/waveform data, or media references, so identifying one typically involves checking the program that created it, inspecting its folder neighbors, noting its size, and opening it in a text editor to see whether it contains real text or binary gibberish.
A file extension like .avf is just the ending that suggests a type helping your system pick icons and default apps, but it doesn’t guarantee the internal format, since the real identity comes from the file’s internal structure; therefore, renaming a JPEG to .avf keeps it a JPEG, and two unrelated tools can both use .avf for different purposes, making the creator app and a text-editor peek (readable vs. binary) the most accurate ways to understand what an .avf file actually is.
To quickly figure out what your AVF file really contains, you want to determine its source program and actual data type because “.avf” isn’t standardized; start by checking where it was obtained and which folder it sits in, since surrounding files often narrow down the purpose, then look at Windows’ Properties → “Opens with” to see what app is associated, and finally open it in a text editor—if you see readable text it’s likely a metadata or config-style file, but if it’s random symbols it’s a binary format tied to the app that generated it.

Also look at the file size: very small AVFs are often metadata or logging artifacts, while large ones can be cache/index structures or exported data, though size isn’t definitive; for the most accurate identification, view the header with a hex tool because common markers like `PK` reveal underlying formats, and when you combine that with context, app associations, text-versus-binary checks, and size clues, you can usually determine whether the AVF is auxiliary, a report, or a specialized data format and what program can open it correctly.
When an AVF file is explained as holding metadata, it means the file contains informational context rather than core media, including items like source paths, timestamps, resolution, codec notes, thumbnail or waveform references, timeline markers, and unique IDs that help software speed up project operations and maintain accurate links, leaving the AVF unplayable in normal apps because it functions as a structured catalog entry, not the media itself.
