I have this same requirement - we want to put logs in a specific root directory that should exist within the environment.

public static readonly string DefaultLogFilePath = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

If I want to combine this with a sub-directory, I should be able to use Path.Combine( ... ).

The GetFolderPath method has an overload for special folder options which allows you to control whether the specified path be created or simply verified.

try  Environment GetEnvironmentVariable  temp

DO NOT use this   System Environment GetEnvironmentVariable  TEMP     Environment variables can be overridden  so the TEMP variable is not necessarily the directory   The correct way is to use System IO Path GetTempPath   as in the accepted answer

System IO Path GetTempPath   is just a wrapper for a native call to GetTempPath     in Kernel32  Have a look at http   msdn microsoft com en-us library aa364992 VS 85  aspx Copied from that page   The GetTempPath function checks for the existence of environment variables in the following order and uses the first path found   The path specified by the TMP environment variable  The path specified by the TEMP environment variable  The path specified by the USERPROFILE environment variable  The Windows directory    It s not entirely clear to me whether  quot The Windows directory quot  means the temp directory under windows or the windows directory itself  Dumping temp files in the windows directory itself sounds like an undesirable case  but who knows  So combining that page with your post I would guess that either one of the TMP  TEMP or USERPROFILE variables for your Administrator user points to the windows path  or else they re not set and it s taking a fallback to the windows temp path
