MacFileSafeguard is a powerful security software that controls the access to your files and folders. You can lock your personal files with passwords by creating simple permissions, in order to stop other users from peeking into your record. Moreover, you can protect sensitive system files from modification or destruction. Locked files or folders are visible to users, but are protected from access by MacFileSafeguard permissions. None can read, write, delete, or execute the locked file or folder. The sub-folders and files in a locked folder are also protected. MacFileSafeguard does not modify or encrypt the protected files, thus it will never slow down the system, and will not endanger your data.
