Which permissions allow users to change and delete files but not create new ones?

• A. Read
• B. Full Control
• C. Modify
• D. Write

Answer: (C)

The permission that allows users to change and delete files but not create new ones is the 'Modify' permission. This permission typically enables users to view the contents of files, edit those contents, and delete existing files. However, it does not permit users to create new files within the directory where these permissions are applied. To understand why the Modify permission is the correct answer, it’s important to recognize its specific capabilities. When a user has Modify rights, they can alter existing files and remove them, which aligns perfectly with the requirement of being able to change and delete without having the ability to create new ones. In contrast, permissions like Read only allow viewing without any changes, Full Control grants all permissions including creating new files, and Write allows new files to be created. Thus, these permissions do not meet the condition of restricting users from creating new files while still allowing modifications and deletions of existing ones.
