Thank you Paddy. I did not think about your test cases. I believe the underscore one is legal according to this site: http://filext.com/faq/file_extension_information.php |

Yes, you are right. My C# code needs to be updated. I will try to do that, when I find time. |

If the ''file extension'' appears '''after''' the last period (using the first example), then the file extension should be <big>'''jpg'''</big>, and not <big>'''.jpg'''</big> (just a nitpick). Also note that <big>'''.jpg'''</big> contains a non-alphanumeric character, namely the period. In various documents that I read, the file extension is to the ''right'' of the last period (with other caveats, of course), and does not include the period. But other sites do include the period, so ... -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 23:26, 4 May 2015 (UTC) |

Also note that the legality of what is a legal file extension depends on the operating system. Windows/95 for instance, greately expanded what is legal. And I can't vouch for the various flavors of *NIX. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 23:26, 4 May 2015 (UTC) |
