# Rename or delete a generated video file

Video files recorded within EthoVision XT are given the same name as the corresponding trial: Trial 1.mpg, Trial 2.mpg, etc. If you want to rename or delete a video file, you must first delete the corresponding trial.

If you want to rename a video file without deleting its trial, make a copy of the video file with the File Explorer and give this copy the new name.

1.Choose Setup >Trial List.

2.In the Trial List, right-click the row corresponding to the video you want to delete and select Delete.

3.In the window that appears:

▪Choose Rename generated video files for backup if you want to rename the file and delete the trial.

▪Choose Delete generated video files if you want to delete the video file and the trial.

important In either case the tracks and the external data files associated with that trial will be deleted!

4.Click Yes to confirm.
