In version 12.7, TETK changed the way it stores files. It now stores all TETK-created files in the subfolder named TE_AppFiles in the scenario directory. When you reopen and then save older scenarios (12.6 and earlier) using version 12.7 or later, TETK will automatically migrate to this structure. However, any scenarios you save in TETK 12.7 and later are not by default compatible with older versions of TETK.
Why did TETK change?
This structure was implemented to more easily keep track of files generated by the plugin and to help you distinguish them from STK-generated information when mixing modeled objects with imported objects.
Can I use an older version of TETK to open a scenario made using 12.7 or later?
AGI never recommends that you open a scenario made in one software version using an earlier version. However, older versions of TETK that don’t use the TE_AppFiles structure will always search the top-level scenario directory for TE-related files. This means that taking all the files in TE_AppFiles folder and placing them in the scenario directory should do the trick. This method also works if you happen to find that TETK 12.7 or later has a hard time finding a specific file in the TE_AppFiles folder. TETK will always do a backup search of the parent scenario folder, so try throwing it in there.
What are the TETK-specific files that exist in TE_AppFiles?
Files that now reside in TE_AppFiles include TETK scenario-level properties, data-derived vehicle ephemeris and attitude, track object properties, and custom scalar files.
