Can I choose or change the installation path? (Install on the D: drive instead of the C: drive for instance)


Like every Windows 10 app, the Microsoft Flight Simulator app's launcher (Approx 1.3GB) will install on the drive set by default (usually, the C: drive). To avoid issues down the line, we recommend keeping the launcher on the drive set by default with all your other Windows 10 apps.

Once you launch the sim for the first time, you'll have the choice to select the Install Packages Path. If your C: drive is small, you can install the official packages (more or less 100GB depending on your version) and the community packages on any drive of your choice (for instance the D: drive). 


WARNING: If you move the packages installation folder after the first installation, you will need to update the UserCfg.opt file. Failure to do so will result in having to redownload the packages every time you launch the simulation.

By default, you'll find the UserCfg.opt at the following location:




C:\Users\YourUsername\AppData\Roaming\Microsoft Flight Simulator

Open the UserCFG.opt file with Notepad, scroll down to the bottom of the page, and update the following line to point to the correct package installation folder (for instance):


 InstalledPackagesPath "C:\Users\YourUsername\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages"


InstalledPackagesPath "C:\Users\YourUsername\AppData\Roaming\Microsoft Flight Simulator\Packages"



If you want to change the default installation drive for ALL your Windows apps instead, follow these steps:

1. Press Windows key + I together to open Settings.

2. Click on System > Storage.

3. Click on Change where new content is saved under More storage settings.

4. Select D: drive (or the drive of your choice) using the drop-down menu under New apps will save to.

You can also install an app and later move the app to a different drive.


To move an app to a different drive:

1. Press Windows key + I together to open Settings.

2. Click on Apps > Apps & features.

3. Click on the app that you want to move, and select Move.

4. Select the destination drive.
