What is an SMI file? An SMI file is a disk image file created by Aladdin ShrinkWrap or Apple Disk Copy in Mac OS Classic (Mac OS 9 or earlier). It contains a disk image that mounts as a disk on the Desktop when opened.
More Information SMI files were designed to enable floppy disks and CDs to be available as digital downloads. The files could be double-clicked, which would then load a virtual disk on the Desktop of the computer. When Mac OS X replaced Mac OS Classic, the "DiskImageMounter" utility was bundled with Mac OS X to mount disk images. Self-mounting images became less popular as SMI files were replaced by .DMG files in Mac OS X.

More Information
SMI file open in GitHub Atom
SMI files always include <SAMI> as their first line of text. The file then goes on to define its subtitles' margin, font, text alignment, and color.
The file's included subtitles begin at the <BODY> tag. Each line of subtitle text is paired with a <SYNC Start=> tag, which specifies when that line of text appears on-screen. Typically, SYNC Start times are written in milliseconds (so a line of text paired with <SYNC Start=3400> will appear 3400 ms into a video).
NOTE: The SAMI format was developed by Microsoft, as an extension of HTML .
