CAR SFX installer is a new feature in TrustPort Archive Encryption 2.5 that allows you to encrypt files into a self-extracting format.
If you want to use SFX Installer you must check the "Create an EXE Archive" box and then check the "Create Installer" box. both in the Encrypt Archive window.
Then you have to select a file, which will be started after installer extracts data to the temporary folder.
The created encrypted file using CAR Installer will have an EXE extension, but when you open it, you will be asked for the password (or you can use -pxxx command line parameter, where xxx is a password) and if it is valid the file will immediately open and be extracted to a temporary folder.
If the file has any comment, it will be displayed automatically when the user opens the file.
