Trail Files (from PTC)
A trail file is a record of all menu choices, dialog-box choices, selections, and keyboard entries for a particular working session. Trail files allow you to view the record of activity so that you can reconstruct a previous working session or to recover from an abrupt termination of a session. Trail files are editable text (.txt) files.
When you run a trail file, the system replays the selections in the exact order in which they were originally made.
Note: Before running a trail file, you must rename it. You cannot rename a trail file within Pro/ENGINEER; on a Windows NT system, use Explorer, and on a UNIX system, use the terminal window to either move or copy the file to the new name.
Rename the trial file that contains the commands used to create the deleted models. If these trail files are no longer available, then you cannot retreive the part. Trail files are created whenever you start a ProE session. These trail files are created and stored in the working directory of your system.
If you find the trail file that corresponds to the part, then copy and rename this file, and run it within ProE. warning, if you dont want to edit the trail file, then ProE will recreate all the step and commands from that single trial file.
