If the operation doesn't throw any exception, it means that it was successful. The list of the possible exceptions is available here :

UnauthorizedAccessException

• The caller does not have the required permission.

ArgumentException

• sourceFileName or destFileName is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.

• -or-

• sourceFileName or destFileName specifies a directory.

ArgumentNullException

• sourceFileName or destFileName is null.

PathTooLongException

• The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.

DirectoryNotFoundException

• The path specified in sourceFileName or destFileName is invalid (for example, it is on an unmapped drive).

FileNotFoundException

• sourceFileName was not found.

IOException

• destFileName exists.

• -or-

• An I/O error has occurred.

NotSupportedException

• sourceFileName or destFileName is in an invalid format.
