A VDF can be opened and re-saved as a VDF, but you can also extract or unpack its contents to move or reuse files contained within; in this respect, a VDF is much like a zip file.
- First, note your VDF Base Directory path. By default, it is the same as your STK User location, but it is worth verifying before proceeding; the path is listed under Edit > Preferences > VDF Save / Load.
- In STK, click File > Open and select your VDF.
When the VDF opens, you have opened a temporary copy. Follow these steps to make a permanent copy in your VDF Base Directory
, which we will assume in these steps is the same as your STK User folder
- Click File > Save As...
- Click the STK User button on the left.
- Use Details to sort by date and you should see the newest folder (with the same name as the VDF), where it has been temporarily unpacked.
- Open the folder and change the Save As Type filter to be .sc.
- Select "<your_scenario_name>.sc" and click Save.
- When prompted, click Yes to overwrite. You now have a permanent copy of the scenario.
Note: In the above step if you're not prompted to overwrite it's possible that you selected a location that was not where the VDF was temporarily extracted and if so this procedure did not capture external files contained in the VDF.
Save As will save the scenario and children objects
Save As in the temp extract location (typically the VDF Base Dir) gets all files contained in the VDF.
Tip: Immediately after you open the VDF, browse in Windows Explorer to the location VDF Base Dir / VDF name folder to see that all the files conatained in the VDF including external files (terrain, imagery, report styles (.rst), .attitude (.a), ephemeris(.e), custom files, etc). You can also just make a copy of that folder while VDF is open.
