On the backup options page (Settings>Update & Security>Backup>More Options), there is a list of folders to include when performing a backup. For example, Pictures C:\Users\me backups all the folders in my pictures folder. This works well.
However, all the new sub-folders in my picture folder are automatically added to the list. I've already set the backup to save my pictures folder and all its sub folders so I don't need all my new sub folders on the list.
To make matters worse, after I go through and remove all the sub folders, they are then automatically added to the exclude list so then I have to go through and remove all of them from my exclude list.
How do I stop sub folders being automatically added to my Windows 10 file history back up list?
