Hefile or High Equipment file, refers to an e-file or equipment file (database with units and their stats) that uses high prestige costs for some units as a means of regulating the size and power of player armies. The cost of units is important, not only in terms of the number of prestige points that must be spent to purchase them, but also because most units count against the overall cap set by a campaign designer on the value of the player's army. The basic idea of Hefiles is twofold: Examples of low cost or Lefiles include the original SSI file and the Waffenkammer efile.
