Thanks in advance.

oops that should be os.path.getmtim e("%userprofile %/dir/file")

Well I can see a few problems here.

First is that putting percent signs around the whole path is
never going to work anyway. You want something like:

"%USERPROFI LE%/dir/file".

Secondly, the expansion of environment variables like
USERPROFILE is done for you by the shell or the command
prompt. You have to do it for yourself if you're opening your
own files. You want something like:

import os
print os.path.getmtim e (os.path.join (os.environ['USERPROFILE'], "ntuser.ini "))

But finally, what do you mean "run on machines where the username is
unspecified"? If you mean: where no user is logged in, then you won't
have a (meaningful) userprofile in any case: it might be the Default User
profile; I'm not sure. But is that what you want?

You *can* use the functions in the win32profile module of the pywin32
packages to find out various things about profiles directories, but things
can get quite complicated if users have roaming profiles and the like.

I think what he meant is where he doesn't know in advance the name of
the user name.

Tim,

I'm surprised you didn't mention your excellent winshell utility. I
use it for this sort of issue all the time where I need to update
files on login and I don't know the user's name beforehand.

The winshell.Deskto p() one has been a life saver and I think the OP
could probably use winshell for their problem. Or I may be completely
off my rocker.

Either way, here's the link: http://timgolden.me.uk/python/winshell.html

"~" appears to look first at the HOME environment variable.
That is not necessarily the same as "USERPROFIL E". On my machine it is
not.

There was quite a debate over that on python-dev earlier
this year. In short, it's not easy to identify exactly what
"~" means on a Windows box. The implementer of that patch
took the view that HOME comes first and then USERPROFILE,
finally HOMEDRIVE/SHARE/PATH. On my machine at work,
the latter should take precedence as they are set via
my domain logon. Other people's mileage may vary. In addition,
the code assumes that the home for any *other* user can
always be derived from the *current* user's home.
Which will not always be the case.

All that is essentially why the user-specific functions
exposed in win32profile rely on a logon token to operate.

(Bit of a rant, but just to highlight that things are
seldom what they seem).

os.environ('USE RPROFILE') should return an info regarding that environment

I guess that, not yet tried.

I found:

from os import environ
r'%(HOMEPATH)s\ My Documents\My Pictures\pycon. bmp'% environ

But 'os.join' is supposedly more correct.

For the record, the %PERCENT% syntax for looking up an environment variable
is just a feature of the XP command shell. It has no meaning to any other
part of Windows.

os.environ is the right answer.

You can use it at the Run command or in Explorer too. If I type
%username% in either place, it opens the following on my XP machine: C:
\Documents and Settings\Mike
