FAQ
What limitations should I know?
In-place write-back needs Chromium File System Access; otherwise a ZIP is exported. Nothing is uploaded.
When might it fail?
The picked root cannot be renamed on disk in the page; missing write permission, collisions, or illegal names also fail.
What should I check when results look wrong?
Confirm Scope, whether the sequence is per-node or cross-tree, and that the preview shows no conflicts.
Any other important notes?
Leaving the page releases the directory handle; close apps that lock the same files before renaming.
