"abcdefghijklmnopqrst" is 20 characters long, resulting in 259 total characters for the successfully created file. If there is a 256 character limit, where is this limit referenced? I can't seem to find any references to it in the Core Reference. In Windows, we can easily create files with filepaths greater than 256 characters; I would also expect this case to be handled successfully by File.open(). (Sidenote: I did move the backup directory to C:\backup, and that worked around the issue)
