Empathy is a special utility for password-protecting any executable file. This utility can modify an EXE file and required a password to run it. Protected files stay protected if you copy them to another location or even to another computer, no matter which operating system do they use.
To use, download and run it (no installation required), select an exe file, for e.g. a program icon from your desktop and choose a password and click on ‘Protect’. You can check the functionality by clicking on ‘Test’ button. If anything happened wrong, you can recover the original file from a backup created by Empathy. The file is in the same directory as the original file. A "BAK" file extension is appended to its name.
Run under Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows 95, Windows 98 and Windows Me.
Remember that Empathy is Postcardware. You can use it freely for an unlimited period, but if you want to use it with all functions, you have to register it by sending the auther a picture postcard. More details and download.[via]
