I've been searching for hours for an answer. Such a simple thing. Huge jumble of partial answers....
Given: Large directory tree structure, folders with files, maybe some empty folders.
Challenge: Move recursively throughout tree. Delete all folders in entire tree that has in name "xyz".
There might be one such folder. There might be one hundred.
Any thoughts greatly appreciated.
