z = file index (= 2 characters: 0..9)
zz specifies the location in memory where the file is stored.
- for standard files: zz = 00...maximum standard files
- for custom files: zz = 00...63 where 00 is reserved for the file ’none .c00’ (file which is loaded when no signal is applied)

yzz is a unique combination. In other words, no two files can exist with the same extension yzz.

To specify more than one file you can use the question mark (?) and (*) wildcard character for x, y and z (or
any other character).

?: This wildcard character can represent any possible character on a particular location.

* : This wildcard character can represent any possible character(s) following the wildcard’s position in the
string.
