FileSystemFileHandle: getFile() method - Web APIs | MDN
Toggle sidebar
FileSystemFileHandle: getFile() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2023.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The getFile() method of the
FileSystemFileHandle interface returns a Promise which resolves to a
File object representing the state on disk of the entry represented by the handle.
If the file on disk changes or is removed after this method is called, the returned
File object will likely be no longer readable.
Syntax
js
getFile()
Parameters
None.
Return value
Exceptions
NotAllowedErrorDOMException-
Thrown if the
PermissionStatus.stateis notgrantedinreadmode. NotFoundErrorDOMException-
Thrown if current entry is not found.
Examples
The following asynchronous function presents a file picker and once a file is chosen,
uses the getFile() method to retrieve the contents.
js
async function getTheFile() {
// open file picker
const [fileHandle] = await window.showOpenFilePicker(pickerOpts);
// get file contents
const fileData = await fileHandle.getFile();
}
