Property Value

The value of the CreationTime property is pre-cached To get the latest value, call the Refresh method.

This method may return an inaccurate value, because it uses native functions whose values may not be continuously updated by the operating system.

If the file described in the FileSystemInfo object does not exist, this property will return 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC), adjusted to local time.

NTFS-formatted drives may cache file meta-info, such as file creation time, for a short period of time. This process is known as file tunneling. As a result, it may be necessary to explicitly set the creation time of a file if you are overwriting or replacing an existing file.
