One-line batch script to delete empty directories
You don’t need a whole 260KB program to do it. This batch file does the trick just fine:
for /f "usebackq" %%d in (`"dir /ad/b/s | sort /R"`) do rd "%%d"
I call it
This is the long-forgotten follow-up to
Performing an operation in each subdirectory of a directory tree
We’re using the same technique as in that article,
but pumping the result through “
| sort /R”
to reverse the order of the enumeration so we enumerate
the directories bottom-up rather than top-down.
This is important for deleting empty directories
because you have to remove the subdirectories before
you remove the parent.
Disclaimer: I doubt anybody actually enjoys working with batch files, but that doesn’t mean that tips on using it more effectively aren’t valid. If you would rather gouge your eyes out than use the confusing command prompt batch language, then you are more than welcome to use the scripting language of your choice instead. At no point in this article am I saying that this is the only way or the best way to do it. But it’s definitely smaller than a 260KB program.
