how to exclude many similar sub-sub-subfolders of the same name from backup
Wrote this question by mistake already somewhere else, think it should be on its own:
I want to save ONE folder sitting in a disk's root.
This folder contains 100+ subfolders (growing a bit each week), and each of them contains three to five sub-subfolders.
Each of those again contains multiple sub-sub-subfolders, whereas always two of them are named "cache" and "trash".
How to backup this one folder and all its subfolders, but exclude ALL sub-sub-subfolders named "cache" and "trash" - without having to manually DE-select 800+ folders under backup options? (and without having to adjust the to-backup-list each week) ?
