I thought this information would be easy to find on google or on this site but can't find it. Sorry in advance if I missed it.
I have a document library accessible by 100+ people and we decide to lock the possibility to delete any folder because of the risks a non-IT skilled person accidentally remove all our files. My idea was to go in the SP permissions level and uncheck something lie 'Delete folder' but it doesn't exist like that. I have reviewed the list several time and can't find to which permission level this right to delete folder is associated to. Below the list of permissions I can modify. Can somebody clarify to me how I can set-up a permission level were people can manage files (create, edit, delete) but can't delete any folder?
Many thanks in advance
PS: the list of permission level:
