Represents the path of the user's home directory.
For Windows, the folder represented by AppData in HKEYCURRENTUSER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Shell Folders in the registry is returned.
If this folder does not exist, it returns the same folder as System.exePath.
This is typically:
For XP C: \ Documents and Settings \
For Vista, 7 and 8 C: \ Users \
Same as filesDir on Android.
