Ok.

$ which sum.exe
/usr/bin/sum.exe

$ /usr/bin/sum.exe
and 
$ sum
  (both just hangs waiting for input)

$ cp /usr/bin/sum.exe copysum.exe

$ ls -l /usr/bin/sum.exe
-rwxr-x---+ 1 sam Users 26624 Dec 21 02:32 /usr/bin/sum.exe

$ ls -l ./copysum.exe
-rwxr-x---  1 sam None 26713 Dec 22 15:19 ./copysum.exe

$ ./copysum.exe
This program cannot be run in DOS mode.

$ find / -name "sum.exe"
/bin/sum.exe
/usr/bin/sum.exe


And I have no alias's to cp. (or any other aliases)

For clarity,

$ which ls
/usr/bin/ls
