How can I find path to given file?

Question

I have a file, for example \"something.exe\" and I want to find path to this file
How can I do this in python?

Answer 1

if you absolutely do not know where it is, the only way is to find it starting from root c:\

import os
for r,d,f in os.walk("c:\\"):
    for files in f:
         if files == "something.exe":
              print os.path.join(r,files)

else, if you know that there are only few places you store you exe, like your system32, then start finding it from there. you can also make use of os.environ["PATH"] if you always put your .exe in one of those directories in your PATH variable.

for p in  os.environ["PATH"].split(";"):
    for r,d,f in os.walk(p):
        for files in f:
             if files == "something.exe":
                 print os.path.join(r,files)
