The kind read-only property of the FileSystemHandle interface returns the type of entry. This is 'file' if the associated entry is a file or 'directory'. It is used to distinguish files from directories when iterating over the contents of a directory.
A string that can be:
'file': If the handle is a FileSystemFileHandle.'directory': If the handle is a FileSystemDirectoryHandle.The following function allows the user to choose a file from the file picker and then tests to see whether the handle returned is a file or directory
// store a reference to our file handle
let fileHandle;
async function getFile() {
// open file picker
[fileHandle] = await window.showOpenFilePicker();
if (fileHandle.kind === "file") {
// run file code
} else if (fileHandle.kind === "directory") {
// run directory code
}
}
