aspire font library

[Hunterland]

Hi all , while waiting for my version 3 dvd to arrive i started going through my font library,and found over time i have a few differant font types in there that do not show up in aspire , and was wondering if there is a way to make them show up, some of the file types are ( CHR, JHF, Auto Cad, v font, class file, html, can any of these be converted so aspire can reconize them or should I just delete them, from the font folder. Thanks for any info ! Don
