TraceLocation > Filename

Edit online

The FileName setting ( Map Settings > TraceLocation > FileName ) specifies how a map trace file is named. A map trace file with a default name is overwritten the next time the map is traced. Specify a custom name or a unique name to compare map trace files across multiple runs of the same map.

Default

The default map trace file name is mapname.mtr.

Custom

Specify a name for the map trace file in the Custom > Value field.

Unique

Automatically creates a unique map trace file name in the format:

Mer_mapname_processKey_mapCounter_hostname.mtr
