File Unknown Outlined

The file-unknown-outlined icon represents unrecognized file types and unknown format indicators in modern applications. This outlined unknown design communicates unidentified files, unrecognized formats, and file type errors, making it ideal for file type warnings, format errors, and unknown file indicators where unrecognized file detection and format identification need clear visual recognition across file management and error handling interfaces.

In modern applications like file explorers or document browsers, you'll see this icon indicating unknown file types and unrecognized formats. It appears in file lists when displaying unidentified files, in upload interfaces when showing unsupported formats, or in cloud storage platforms like Dropbox and Google Drive where outlined unknown icons indicate unrecognized files and format compatibility issues.

From a file identification perspective, the outlined treatment communicates more than simple file unknown status - it specifically indicates unrecognized files, unsupported formats, and the error nature of unknown file type displays. This standard appearance helps users identify problematic files and format compatibility issues within file systems and document libraries.

File Unknown Outlined is one of 830 icons in Ant Design Icons, made by HeskeyBaozi and released under MIT. It is drawn on a 1024 × 1024 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds FileUnknownOutlinedIcon to components/icons/ant-design-file-unknown-outlined.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed FileUnknownOutlinedIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the File Unknown Outlined icon, or any of 830 Ant Design Icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 1024 × 1024 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="File Unknown Outlined", so screen readers say what it does.

Yes. FileUnknownOutlinedIcon passes every SVG prop to the svg element, so <FileUnknownOutlinedIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. MIT allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: MIT only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Ant Design Icons, HeskeyBaozi and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are file, error, format, outlined, question and unknown. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for File Unknown Outlined in another set.

Ant Design Icons draws many icons in several styles: Filled and Twotone next to the default. Open the library and pick a style above the grid to see File Unknown Outlined's siblings in it.
