In the entire world, Folio (F. 
, Ff. 
, Folio 
) is a common gender-neutral forename. The first name Folio is characteristic of Indonesia, where it is quite a rare gender-neutral name, Bangladesh, where it is quite a rare primarily boy's, but very infrequently female name, and Taiwan, where it is quite a rare masculine name. Not in comparison with a country's population, this name is the most popular in Indonesia, Bangladesh, and China. Much less frequently, Folio is the last name as well as the forename.
Folio is also a name for the fictitious and mythical characters: F. D. C. Willard , the cat, described by his owner Ph.D. Jack H. Hetherington as a United States-based scientist and co-author of works on cryogenics; Richard Schiller , the character from Vladimir Nabokov's Lolita; F.U. Gary Gray , the minor character from the animated television show Drawn Together; F. H. Dougla , the musical character in the musical Going Up by Louis Hirsch; a chronic bettor and F. W. Knopp , the operatic character in the operetta Saison in Salzburg, among other works.
