Windows user A will not know what their home directory is and will respond as described. Windows user B will assume that it is their "my documents" folder, which may or may not be the case, because: Windows user C will know that there are effectively three home directories in Windows (/users/username, /users/username/documents, and /users/username/appadata/local) but that won't help anybody determine which one some program actually put the goddamn file in.
