Btw, I think I have figured this out now...
Try this...I think it has worked for me but have to further check.
D:\Main Folder\Sub A\Sub 1
D:\Main Folder\Sub A\Sub 2
To ensure the permissions get changed on Sub 1 & 2, select "Main Folder" and go into Properties > Security > Advanced > "Change Permissions" > Select Administrators > Check "Replace all child object permissions with inheritable permissions from this object"
Once you press "Ok", it should go through and change each folder and file.
As I said, I still have to double check this, but sounds like this maybe it!
