[5] Subsequent charters frequently call File as chancellor and "magister", demonstrating the prestige of his office, even though he was not a member of the royal court.
[8] File participated in the royal campaign commanded by Ban Denis Türje in 1244 to the coastal city of Spalato (present-day Split, Croatia), which rebelled against the Hungarian rule.
According to contemporary chronicler Thomas the Archdeacon in his work Historia Salonitana, File ("Philetus") led one of the companies which successfully besieged the city.
[3] File acted as a pristaldus (royal commissioner or "bailiff") for the Hungarian monarch in 1245, when registered certain nobles to the ownership of Rakovac.
[3] The Miskolc kindred possessed lands in Borsod County in Northeast Hungary, and File was also a wealthy landowner in the region.
Simultaneously with his social ascension, File and his family sold their several lands in Borsod County and moved their primary interests to Slavonia.
[11] File's service in the ducal court of Coloman contributed to the acquisition of large estates by him and his brothers in Slavonia, especially Valkó County.
Béla IV confirmed this donation to them in October 1244, rejecting the claim of Bertrand Bajóti and his wife Ahalyz (widow of Batiz Negol then Solomon Atyusz).
[3] File was granted several estates near Pakrac in 1239 – Daróc (present-day Vardarac, Croatia), Ködmen, Rücs and Donát –, which were formerly belonged to the ownership of Abraham Tétény.
[3] King Béla donated the estates Mikola and Szentmárton near Svinjarevci and Vukovar to File and his brothers in October 1242, fulfilling the promise of the late Coloman.
Béla IV confirmed Thomas and Peter as the owners of "Derinemty", Mikola and Szentmárton for the merits of the late File in January 1249.
Around 1263, Stephen handed him 300 silver marks with an order to give it to his distant relative Panyit Miskolc (son of Paul) to finance his legation to the Golden Horde.
