What this file tool does

Walk a folder hierarchy with explicit local permission and report directories that contain no files or subfolders.

With File System Access support, the tool recursively enumerates directory handles. Strict mode finds directories with zero entries; no-files mode finds directory subtrees containing no files.

Processing stays on this device. True empty folders cannot be detected from a standard webkitdirectory upload because browsers omit directories with no files. Use the directory-access button in a supported browser.

Example and practical tips

Practical example

Directory permission lasts according to your browser's security policy.

Frequently asked questions

How can a browser find truly empty folders?

A supported browser can grant a page a directory handle that includes directory entries, even when a folder contains no files.

Why can’t normal folder upload detect empty folders?

The standard upload FileList contains files and relative paths but does not include standalone empty-directory entries.

Does this tool delete empty folders?

No. It only creates a report, so any deletion remains a separate manual decision.

What is the difference between strict empty and no files below?

Strict means a folder has no direct entries; no files below also matches folders containing only empty subfolders.

Which browsers support directory access?

Support varies. If showDirectoryPicker is unavailable, this page clearly reports that reliable empty-folder detection cannot run.
