Searches and deletes empty directories recursively below a given start folder. Let's you check all empty directories before deleting them. Supports multiple delete modes (including Delete to recycle bin). Allows white and black listing of directories by using filter lists. Can detect directories with empty files as empty.
I checked the database and it wasn't listed. However, I should have also checked the forums. Anyway, I have found this program useful. The current version, ver 2.2, is listed as portable on the website. I'm unsure whether a portable version existed in 2008 when it was submitted by Baas.
