Funny, one of my Delphi programs does this..

Given a long file name pointed to by ES:DI, point DS:SI to the address of
the result buffer, set CX=1, AX=0x7160 and call int 21.

If carry is not set on return, then the result buffer has the short name.

To go the other way (short to long), set CX=2

Uh... this is a 16-bit program, your mileage will vary.. ;-)
