Hi all.

Here's a little script to delete empty all empty (less than 100kB) folders. I used 100kB instead of 0kB as having empty folders within other empty folders increases the size.

The user is prompted to select the folder containing all the empty folders to be deleted.

Hope this helps someone

Nice Idea!

Here is my variant that loops "inside-out".. should be faster

That's funny, I also made my own version of this lately. daorc, it's important that you check the errorlevel after the fileselectfolder command. If the user clicks the Cancel button in the fileselectfolder window, your WhichFolder variable remains empty which could potentially have some nasty side effects! Also, deleting all folders less than 100 kb seeems quite risky as small files can be very important and a file of 100 kb can hold a whole lot of text.

I'm sure Skan's code is very good, but as often is the case I don't understand it.

Skan: What do you mean by "inside-out"? Does it mean that you start deleting empty folders at the "deepest" level and then work your way back up the folder tree? I think I had problems with my script because if a folder contained an empty subfolder, only the subfolder would be deleted. If I would run the script again it would delete the "now-empty" folder as well.

Here's my version:

Exactly.. to avoid the following problem mentioned

That's what I thought but I wasn't sure. So this line is the key to deleting the "deepest" folder first:

It sorts the filelist in reverse alphabetical order which means the folders with the longest paths (Deepest folders) are sorted before the folders with the shortest paths. A clever and elegant solution -well done!
