stop users from deleting a file

[Admiral208]

I think I am missing something really obvious here...

I am trying to make a file 'read only' in a folder.

I have modified the permissions as follows...
- removed inheritance of permissions from parent folder.
- given the staff group read/read & execute only.

Am i right in thinking this is enough? when I test it, a staff user can still delete the file.

What am I missing?

thanks
James

are your staff
members of a administrator group?

[Admiral208]

had to check but, no. They are not.

ive even tried explicitly denying the delete permission and I can still delete the file.

Have you gone into Advanced security settings on that file and made sure Delete is unticked? Should be, but it's worth checking.

[round2it]

thats where i would look too

its either a permission or a member of a admin/poweruser group

Make sure you're applying the permissions to the files inside the folder, and not just the folder.
