Add Restrictions on Folders in Certain Drive

I want to restrict my user in using only two folders in a certain drive. For example, I just want him to have an access in drive D where there will is only 2 folders; 1 FINAL and 1 WIP. I want to add some restriction on these two folders especially the Final folder.
I also want the following to happen:
a) The user should not have any permission or control in deleting the folder.
b) One problem is he could not overwrite the file. Every time he would try saving the file in Final folder, he could save it initially but if he will modify it he could not save it with the same filename anymore.
Can someone please help me ASAP with this thing? Thanks!
