Many times the need to have a file added to WKO5 comes up but for one reason or another a good file already exists or for a different reason this file is needed but its data shouldn't be counted towards the athlete's training progress.

For example, sometimes one event is recorded with two different devices but only one should count towards the athlete progress.

Other times, a file is known to have bad data, but deleting it would make things worse because even though some data is bad, other data is not, e.g. topology may be good, but power would not be.

Other times, taking out the bad data (power or HR spikes for example) is too time consuming and just moving the file to this "extraneous" category would facilitate analysis.
