As far as I can recall from my //c days, these are/were the suffixes:

.sdk ShrinkIt disk archive
.shk ShrinkIt file archive
.bsc BinSCIIed file archive
.bsq BinSCIIed ShrinkIt archive
.bny Binary II archive
.sq  Squeezed file
.bqy Binary IIed Squeezed file

I don't think I ever remember seeing ".bsq" around before BinSCII.
