Read only file or folder

Hi, friends. Could someone show a reliable way to change a file or folder so it cannot be modified or deleted? I am not talking about for different users or groups. I just want the local files “read only”. So that they can be used or read by their applications. However, I want to make the file read only and not able to change or be deleted. I am aware that some files (e.g. MS Word) have to be modified to be opened by their application. I can pass on those. All ideas or suggestions are welcome. Thanks for any help

Properties -> Security -> Edit to change permissions.

Click Add, enter Everyone for the name and click OK.

Set permissions for the new entry to Allow Read, Deny Write:

Super! Thanks so much

After testing more, I saw that the files this applied cannot be modified. That is part of what I wanted. However, I later tried to delete a file/folder and it did delete. Should that be that way or is something else needed? Thanks

Whether or not you can delete a file is a down to the permissions on the parent folder. If that denies deletion in a similar way, it'll stop the file (and all others in the same directory) being deleted by that account.
