I use a routine that finds removable drives and puts them in an option group. You might be able to adapt it for a combo box and for all types of drives. Or you might want to use getdir().

local nowno,i,curtop
nowon=1
curtop = 8
for i = 65 to 92
if inlist(drivetype(chr(i)),2)
decl thisform.drives(nowon,2)
thisform.drives(nowon,1) = chr(i)
thisform.drives(nowon,2) = "Drive "+chr(i)
thisname = "opbutton"+allt(str(nowon))
thisform.optiongroup1.addobject(thisname,"optionbutton")
thisform.optiongroup1.&thisname..caption = "Drive "+chr(i)
thisform.optiongroup1.&thisname..width = 100
thisform.optiongroup1.&thisname..top = curtop
thisform.optiongroup1.&thisname..visible = .t.
thisform.optiongroup1.&thisname..left = 10
curtop = curtop + 21
if nowon > 1
thisform.optiongroup1.height = thisform.optiongroup1.height+21

nowon = nowon + 1
if nowon = 5
exit
