The new name of a file is build from the basename and an index-number. How
many digits this number has, you may specify with the Digits-Gadget. If the
actual number has less digits, than you specified, it will be extended with
leading zeroes (326 -> 0326). If it has too many digits, the setting will be
ignored and the number will be appended to the basename, as is.
The following examples should make this more clear
| Basename | Index | Digits | new name |
| Anim. | 83 | 4 | Anim.0083 |
| Pic_ | 123 | 3 | Pic_123 |
| Frame- | 4321 | 2 | Frame-4321 |
