Files and folders should be protected so that other PC users like your kids, parents, family members, co-workers and friends cannot access, read, view, copy, move or delete files without your permission (password). Files left unprotected can lead to theft, data loss and breaches of privacy. This can cost you money, lost time and inconvenience, even your job. Folder Lock not only protects files from unauthorized users but also safeguards them from viruses, trojans, worms, spyware, malware, etc., and from network computers and hackers who may try to steal your files when you connect to the Internet. It also prevents illegal copy or duplication of your material.
