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 USVString 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.
var fullPath = FileSystemEntry.fullPath;
A USVString indicating the entry's full path.
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.
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.
