Find a executable file path programmatically and fast

I want to find a .exe files path programatically in Java, for example:

  • Skype.exe is entered into a program to find the direct path to it
  • Program does an algorithm that finds the file path
  • Program returns the file path C:\Users\Public\Desktop\Skype.exe

A method I have tried is sorting through the systems files until "skype.exe" is found, but that takes up a lot of time and resources.

Is there any hack that could make it almost instant, like maybe a Win_Api function/cmd command or is sorting through the file system until the program is found the only way?

If you want to know WHICH executable is being executed from the command line when you type . Use the which/where commands..

Unix/linux/Mac OSX Possix <which>

which chmod which cd which ls which myprogram

returns returns nothing if no such program file exists.

for Windows use where <where> /? for help on this command

If you don't have an executable but an alias or some sort of environment function/procedure/shell command.. use the <type> command on Unix/linux/Mac OS X. That will tell yo if you are dealing with an alias, environment function, or executable.
