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.

The path parameter is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.

NTFS-formatted drives may cache file meta-info, such as file creation time, for a short period of time, which 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.
