Why does Windows say I need permission to delete files

Question

I'm logged in as an admin on my Windows 10 machine. When I go to delete a folder, it says I need permission. I set the permission on all files in the folder and its subfolders so that anyone can delete the folder, yet this didn't help. I also notice that the folder is read-only. I remove the read-only from it and its subfolders, but it still does not delete the folder and files in the folder still exist. Only if I manually start deleting files one by one am I able to delete the folder.

Why is this happening? If I'm an admin and have set full permission on the files and folders, why is it telling me I need permission?

Answer 1

I noticed that the parent folder was read-only. Even though I was deleting only the sub folders within the parent folder, Windows refused to delete all of them if the parent folder had the read-only attribute set. By removing the read-only property on the parent folder was I able to delete all the sub folders.
