← DictionaryFile Format
also called file type
The encoding standard of a file, which determines how it can be used.
What kind of file it is, and where it works.
What It Is
File Format sits on the Technology side of the work, in the Files area. What it actually refers to is the encoding standard of a file, which determines how it can be used.
It is a label with a settled working definition, so the value is in using it the same way every time. That is the version worth keeping, because it survives contact with a real project.
How It's Used
Most of the time File Format is used in build decisions, tooling and the plumbing behind a working system. It is usually discussed together with Vector File, Raster File and Image Optimisation. The practical test is whether everyone in the room means the same thing by it.
Why It Matters
Ignoring File Format rarely fails loudly — it fails slowly. When it is unclear, small technical debts compound into a rebuild. It is worth pinning down before anyone builds on top of it.
Think of it as a name on a box. Open the box and this is what is inside: What kind of file it is, and where it works.
Termshift™
How the meaning shifts depending on who is using it, and where.
Practitioners use File Format as shorthand and expect no explanation — the encoding standard of a file, which determines how it can be used.
Outside the industry, most people would just say: what kind of file it is, and where it works.
The Bottom Line
Treat File Format as a decision, not a description. What kind of file it is, and where it works.
