ST (or .ST) is a format used for raw floppy disk image files for Atari computers.

Though other formats are common, ST files typically use the Atari ST style of FAT12, making them pretty much the same as IMA.

Software

MSA Converter (Windows application)
Floppy Image v1.02 (Windows binary) can extract files from ST images, awkwardly: (no need to install the driver) "Open image file", "File transfer", select a "Dest Dir", select file(s), "Extract".
Supported by some Atari emulators.
