If you try to run a program through Wine's CLI, you sometimes cannot take advantage of autocompletion because it expects a Windows-like path, usually located on the Z: drive. You can use a little script such as this one to abstract this chore away:

#!/bin/bash
file=`realpath "$1" 2>/dev/null`
/usr/local/bin/wine "c:\Program Files (x86)\coolpro2\coolpro2.exe" "z:${file//\//\\}"
