Hello,

I am trying to make an application in C # this application will read txt or xml files in some directories and I would like these files not to be editable by other users but only by a few people. This is why I had thought of zipping the files with a password and only people who know the password will be able to make changes to the files.
I also thought about encrypting these files, but the problem is that the file will still be accessible to users, I mean they will be able to open the file, even if the content will be unreadable, they will be able to edit it and then close it again .

My question is: what is the best way to do not make certain files editable for users but only for certain users?
Do you necessarily have to password protect files?

Thank you.
