There are some file texts that the program generates automatically, (e.g. the lines of the Totals table, the transactions on the account card, and the printout of the Enhanced balance sheet); in this tab, the user can indicate the language for these texts (usually the same as the creation language).
This is the language chosen and selected when the user creates an accounting file; this language is used for the column headers. If the user wants to change the creation language, then it is necessary to convert the file to a new one using the Convert to new file command in the Tools menu.
