This new feature allows you to synchronize your aircraft folder with whatever you are using as a source to update from.

XPlaneUpdate does not normally delete any files that are not part of the source fileset (on our servers or otherwise).

Austin often changes the aircraft that he includes with X-System - both their names / locations, and the files that make up each aircraft.

If you use XPlaneUpdate to install just the "newer/different" files, you can end up with old aircraft in your Aircraft folder that cause the current version of X-Plane problems as Austin has made changes to X-Plane that may make old aircraft incompatible.

We have now added a new menu item:

that allows you to synchronize your Aircraft folder after download/installation.

If you check this item and hit start (you may need to use the Clear File Cache menu item to guarantee some files get downloaded), after XPlaneUpdate has downloaded/installed everything, you might see something like this:

This list allows you to fine-tune (remove) any files you don't want XPlaneUpdate to delete, and you'll also get a confirmation dialog after this to make sure you don't accidentally delete important aircraft.

You'll note in this example, that we have created a folder in Aircraft called "_mine".

We suggest that you do the same and do NOT put your downloaded aircraft into the standard Aircraft folders (General Aviation, Heavy Metal, etc.).

There are 2 reasons for this:

1. It makes it easy for you to keep track of what are your downloaded aircraft versus "standard" x-system aircraft.
   
   
2. It makes it easy to tell XPlaneUpdate to ignore your "_mine" aircraft folder and any contents.

The Syncrhonize Aircraft feature will use your Ignore List and skip over any aircraft that are in your ignore list when synchronizing.

Here's an example:

SO, before using the Synchronize feature, we would suggest that you:

1. Create a folder like "_mine" in your Aircraft folder
   
   
2. Move or copy your aircraft (that you have downloaded or that you want to keep) into this folder. You can add subfolders like General Aviation, etc. if you wish. to keep Aircraft/_mine organized
   
   
3. Add Aircraft/_mine to the Ignore List (choose Manage Ignore List from the menu...)

If you use the above technique, your Aircraft folder should always end up with "official" aircraft released by Austin, and Aircraft/_mine will be ignored by XPlaneUpdate.

If after using this feature, you have problems with X-Plane and any of your Aircraft/_mine aircraft, you can now easily move your _mine folder out of the Aircraft folder to get up and running, and then gradually add in your aircraft to find which aircraft(s) are causing problems.

Please use caution with this feature so that you don't inadvertently delete any important aircraft! If you do, that's your fault! :-)
