Getting rid of Archive files. Options

[Old Geaser]

Have not been on here for a while.

On all work orders, after loading the wo in Train Store I always use Activity Master to see if I have all of the equipment and to check the engines. When I check Load a activity in Activity Master, I have about 8 column of archived act files. I know I can click the button and go to the end where the active wo is, but what is the best way to get rid of all of the archive files. Now if I cannot delete these files, it really will not bother me, but is there a way to clean up there archived files? Thanks
