Windows prevent folder deletion

Suppose we have following folders structure:

C:\Media
├───Music
└───Video

And we want:

• Disallow any modifications on Media folder
• Allow any modifications in Media subfolders

First of all we need to Disable inheritance on Media folder

While disabling inheritance you will be asked what you like to do with the current inherited permissions, choose Convert inherited permissions into explicit permissions on this object

Now remove Users Special permissions (they allowing Users group create files and folders)

At this moment users group will be able to access all items but will not be allowed to modify anything

Now you need Disable Inheritance on Music and Video folders as described above.

And add new special permissions for Music and Video folders:

At this moment users are not allowed to modify Media folder but allowed to modify Music and Video folders content.

If for some reason you want also to make the same for your own user you should repeat all steps above but for Administrators group, also you should remove CREATOR_OWNER permissions.
