MFI works in Windows 3.x and Windows 95. It does not work in Windows NT or 32 bit file access of Windows 3.11 (Windows for Workgroups). "Makes Files Invisible" (MFI for short) makes any files or programs you choose completely invisible to those without your password! To the un-authorized user these invisible files and programs might as well not exist. They don't show up in file listings, programs can't find or open them, and they can't be run, deleted or modified. Yet, just enter your password and you'll instantly have complete and normal access to all your files. There's no need to un-hide each file individually. And MFI is totally transparent. No one need know your invisible files even exist. If you share your computer then you need MFI. Use it to protect files you don't want others to delete, modify, view, or use. Keep your important files safe. Make them invisible with MFI! Would you like to install MFI now?
