powershell - power shell remove-item recurse sub directory 3 level down -

i can't figure out way recursively remove folders except sub-sub directory in each folder called "broadcast"

dir ->subdir1 -->main -->broadcast ->subdir2 -->main -->broadcast ->test 

i want keep subdir#\broadcast folders , test folder. problem code below removes subdir1 , subdir2 in few recursion below, removes sub-sub directory

get-childitem -path  $copy_file -recurse | select -expandproperty fullname | {$_ -notlike '*broadcast\*'  -and $_ -notlike '*testing*'} | sort length -descending | remove-item -force  

i can't use -force /a because list when sort includes subdir1 , subdir2...

it prompt me "this item has children..." [y] yes [a] yes all... [l] no 

i want automatically select l

any suggestions? thank in advance... did through couldn't find exact solution looking for.

this exclude 'broadcast' folder (you can replace your) , can pass object remove-item

get-childitem -path d:\ -recurse -exclude @('broadcast') -directory | foreach-    object($_){ write-host $_.fullname }
