FileSystemEntry.fullPath

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The read-only fullPath property of the FileSystemEntry interface returns a DOMString specifying the full, absolute path from the file system's root to the file represented by the entry.

This can also be thought of as a path which is relative to the root directory, with a "/" prepended to it to make it absolute.

Syntax

JavaScript
var fullPath = FileSystemEntry.fullPath;

Value

A DOMString indicating the entry's full path.

Example

This example shows a function which is called with a file system; it then gets a FileSystemFileEntry for a file named data.json and returns its full path.

JavaScript
function gotFileSystem(fs) {
  let path = "";

  fs.root.getFile("data.json", { create: true, exclusive: true }, function(entry) {
    path = fullPath;
  }, handleError(error));

  return path;
}

Obviously, this is somewhat contrived, since we know that the file's full path is "/data.json", having just looked it up ourselves, but the concept holds up for scenarios in which you don't know it.
