Simple File Encrypt

Brilliant definitely worth the small charge A✓✓✓✓✓✓✓

The encryption speed is ok but I am disappointed at the overall working of the app. How is it that encrypted file are numerically renamed, therefore one can not even recognize the files in the output folder. This same set back has made it impossible for the app to encrypt multiple files at the same time. Please fix this, so that encrypted files retain their original names. Also make it that multiple files can be selected and encrypted at the same time.
