Looks like this is a SMB (Windows) share.

I'd recommend to use raw strings for entering Windows file names, like
this:

    r"\\somecomputer\someshare\foo\bar\info.txt" 

As you can see, with raw strings you don't have to escape the
backslashes with an additional backslash, which has the additional
benefit that you can just copy filenames you've got in your Explorer or
Windows commandline into your Python script.

For debugging, you could try to issue os.listdir() on the parts of the
directory tree, like:

os.listdir(r"\\somecomputer\someshare")
os.listdir(r"\\somecomputer\someshare\foo")
os.listdir(r"\\somecomputer\someshare\foo\bar")

This way you should be able to find out where a problem with a wrong
path component or insufficient access permissions is located.

If it's a network share, "open" is the function to use.
