# How To Update
Before updating or reinstalling the E-Jets, we strongly recommend that you delete all E-Jets files - including those that remain after a standard uninstallation. This refers to the so-called work folder, which is stored under your computer user directory. This folder acts as a cache for the aircraft. With too many updates, this cache can easily get messed up and lead to strange problems after an update.
To make this process as easy as possible for you, we have created a portable app, that takes care of this for you. Download and simply run it. Then select WASM and delete . It also has some cache clean-up functions that you should only execute when requested by our support team.

Don't worry, saved settings of the EFB, such as Simbrief username or throttle configuration, etc., will remain intact. You won't need to reconfigure all your settings.
{% endhint %}
## Update Flow
1. Uninstall our aircraft entirely.
2. Run the fss support app and delete the wasm folders.
3. Start MSFS and load a flight in any other aircraft.
4. Close MSFS.
5. Install our aircraft again.
