' NOTE:
' - All path returned by us will NOT have the Directory Separator Character ('\') at the end.
' - All path accepted by us will NOT consider the meaning of Directory Separator Character ('\') at the end.
' - Parameter accepting path will accept both relative and absolute paths unless specified.
' Relative paths will be resolved using the current working directory.
' - IO.Path.GetFullPath is used to normalized the path. It will only throw in case of not well-formed path.
' - Hidden Files and Directories will be moved / copied by Framework code.
'
' - On both Read and Write, we use the default Share mode that FX uses for the StreamReader/Writer, which is Share.Read.
' Details on what share mode means:
' When a call is made to open the file, the share mode not only means that the caller wants to restrict every call
' afterwards, but also every call before as well, which means that the caller will fail if any calls before it
' already obtained a conflict right.
' For example: if this call succeeds,
' Open(FileA, OpenMode.Write, ShareMode.Read)
' Although it is sharing FileA for reading, if the 2nd call is
' Open(FileA, OpenMode.Read, ShareMode.Read)
' the 2nd call will fail since it wants to restrict everybody else to read only, but 1st caller has already obtained
' write access.
' So the default behavior is fine since novice Mort can't run into trouble using it.
'
' - All IO functions involving ShowUI have dependency on Windows Shell and sometimes have different behavior.
' - CopyDirectory will attempt to copy all the files in the directory. If there are files or sub-directories
' that cause exception, CopyDirectory will not stop, since that will leave the result in unknown state.
' Instead, an exception will be thrown at the end containing a list of exception files in Data property.
' - MoveDirectory behaves the same so MoveDirectory is not equal to calling CopyDirectory and DeleteDirectory.
' - Overwrite in directory case means overwrite sub files. Sub directories will always be merged.
'
' Shell behavior in exception cases:
' - Copy / Move File
' . Existing target:
' Overwrite = True: Overwrite target.
' Overwrite = False: Dialog Yes: Overwrite target.
' No: Error code 7. ERROR_ARENA_TRASHED
' . Existing target and Read-Only (Framework will throw).
' Always ask. No: Error code 7. ERROR_ARENA_TRASHED
' . OS access denied: Error code 1223. ERROR_CANCELLED
' - Copy / Move Directory Existing target:
' . Has an existing file:
' Overwrite = True: Overwrite file.
' Overwrite = False: Dialog Yes / Yes to all : Overwrite target.
' No: Leave and copy the rest.
' Cancel: Error code 2. ERROR_FILE_NOT_FOUND.
' . Has an existing file and Read-Only (Framework will throw).
' Behave as when Overwrite = False.
' . File in source same name with directory in target:
' * Copy: Error code 1223 ERROR_CANCELLED.
' * Move: Overwrite = True: Error code 183. ERROR_ALREADY_EXISTS.
' Overwrite = False: Ask question Yes: Error code 183.
' Cancel: Error code 2.
' . Directory in source same name with file in target:
' Error code 183 in all cases.
'
' NOTE: Some different behavior when deleting files / directories.
