Community Folder Management
Estimated Lesson Time: 60–70 Minutes
Lesson Overview
By this point in the course, you’ve learned how to optimise Windows, graphics settings, drivers and benchmark your simulator professionally.
Now it’s time to focus on one of the biggest causes of performance problems, crashes and compatibility issues in Microsoft Flight Simulator:
The Community Folder.
For many users, the Community Folder starts small.
Perhaps just a few liveries or an airport.
Months or years later it can contain:
- Hundreds of liveries.
- Dozens of aircraft.
- Airports.
- Utilities.
- Navigation enhancements.
- Libraries.
- Scenery.
- Ground handling software.
While these add-ons dramatically improve the simulator, an unorganised Community Folder can quickly become one of the biggest causes of:
- Long loading times.
- Reduced performance.
- Simulator crashes.
- Missing scenery.
- Duplicate objects.
- Conflicts between packages.
- Difficult troubleshooting.
In this lesson, you’ll learn how Microsoft Flight Simulator loads add-ons, how to organise them efficiently and how to build a Community Folder that’s easy to maintain, troubleshoot and optimise.

What Is the Community Folder?
The Community Folder is the primary location where Microsoft Flight Simulator loads third-party content.
Whenever the simulator starts, it scans this folder and loads every compatible package it finds.
These packages can include:
- Aircraft.
- Airports.
- Liveries.
- Utilities.
- Navigation data.
- Scenery enhancements.
- Libraries.
- Terrain modifications.
- Ground handling tools.
Think of the Community Folder as your simulator’s expansion library.
Everything inside it is available to the simulator every time it launches.
How MSFS Loads Add-ons
When Microsoft Flight Simulator starts, it scans the Community Folder and reads the information contained within each package.
The simulator checks:
- Package structure.
- Manifest files.
- Layout files.
- Dependencies.
- Version information.
It then loads compatible packages into the simulator before you begin flying.
The more add-ons installed, the longer this process may take.
This is why Community Folder size can directly influence simulator startup time.
Why a Messy Community Folder Causes Problems
As your collection grows, it becomes harder to manage.
Common problems include:
- Duplicate airports.
- Outdated packages.
- Missing dependencies.
- Conflicting scenery.
- Broken utilities.
- Unused liveries.
- Multiple versions of the same add-on.
A poorly organised Community Folder makes troubleshooting extremely difficult because it’s no longer obvious which package may be causing an issue.
Good organisation saves time and reduces frustration.
Understanding Package Priority
Sometimes two packages attempt to modify the same airport, scenery area or asset.
This can lead to:
- Missing buildings.
- Floating objects.
- Flickering scenery.
- Duplicate taxiway signs.
- Terrain issues.
Package priority determines which package takes precedence when more than one modifies the same content.
While Microsoft Flight Simulator handles much of this automatically, conflicts can still occur if incompatible add-ons are installed together.
The simplest solution is often to remove or disable one of the conflicting packages.
Identifying Conflicting Add-ons
A conflict occurs when two or more add-ons attempt to change the same simulator content.
Examples include:
- Two versions of the same airport.
- Marketplace and Community versions installed together.
- Multiple terrain enhancements for the same region.
- Duplicate navigation data.
- Conflicting airport layouts.
Symptoms may include:
- Missing jetways.
- Floating buildings.
- Terrain spikes.
- Broken taxiways.
- Crashes during loading.
When troubleshooting, temporarily disable suspected add-ons one at a time until the issue disappears.
Duplicate Scenery
Duplicate scenery is one of the most common Community Folder mistakes.
For example:
You install:
- Marketplace version of Heathrow.
Later you install:
- A newer Community version.
Both now attempt to modify Heathrow.
The simulator may load conflicting files, resulting in graphical issues or unexpected behaviour.
Always ensure that only one active version of a scenery package is installed.
Duplicate Libraries
Many scenery packages rely on shared object libraries.
Installing multiple versions of the same library can cause compatibility issues.
Although libraries are generally small, it’s good practice to:
- Keep only the latest compatible version.
- Remove obsolete copies where appropriate.
- Follow the developer’s installation instructions.
Maintaining up-to-date libraries helps prevent missing objects and scenery errors.
Outdated Packages
Microsoft Flight Simulator evolves constantly.
After simulator updates, some add-ons may become incompatible.
Outdated packages can cause:
- Missing textures.
- Visual glitches.
- Crashes.
- Reduced performance.
Regularly check trusted developers or marketplaces for updates to your installed content.
Empty Folders
After uninstalling or moving add-ons, empty folders may remain.
Although they usually have little impact on performance, removing them keeps your Community Folder tidy and makes navigation easier.
A clean folder structure also reduces the chance of confusion during troubleshooting.
Disabling Add-ons Correctly
When testing or troubleshooting, avoid deleting add-ons immediately.
Instead:
- Temporarily disable them using your add-on manager or by moving them out of the Community Folder.
- Restart the simulator.
- Test again.
This approach allows you to identify the source of a problem without losing your installed content.
Always disable one add-on at a time during troubleshooting so you can isolate the cause.
Add-on Linker Software
As your collection grows, manually moving files becomes time-consuming.
Tools such as MSFS Addons Linker allow you to organise add-ons outside the Community Folder and activate only those you need for a particular session.
Benefits include:
- Faster startup times.
- Cleaner Community Folder.
- Easier troubleshooting.
- Different profiles for different flying styles.
- Reduced risk of conflicts.
Rather than loading hundreds of unused add-ons, you can activate only the content required for your flight.
Creating Add-on Profiles
One of the most effective organisational methods is creating separate profiles.
For example:
Airline Profile
Includes:
- Airliners.
- Airline liveries.
- Major airports.
- GSX.
- BeyondATC.
- FSLTL.
General Aviation Profile
Includes:
- GA aircraft.
- Regional airports.
- Bush scenery.
- Smaller utilities.
VFR Profile
Includes:
- Photogrammetry enhancements.
- Landmarks.
- Bush strips.
- Scenic airports.
- Mapping tools.
Switching between profiles keeps the simulator lightweight and reduces unnecessary loading.
Organising Your Community Folder
A logical structure makes future maintenance much easier.
Suggested categories:
Airports
All airport scenery.
Aircraft
Aircraft packages only.
Liveries
Airline and aircraft liveries.
Utilities
GSX.
Toolbar Pushback.
BeyondATC.
AutoFPS.
Weather tools.
Libraries
Shared object libraries required by scenery packages.
Keeping these categories organised makes it much easier to identify missing or conflicting content.
Startup Loading Times
Every package loaded at startup increases the amount of work the simulator must perform before reaching the main menu.
Large Community Folders can increase loading times significantly.
Reducing unnecessary active packages often results in:
- Faster startup.
- Simpler troubleshooting.
- Cleaner simulator environment.
While the impact on in-flight FPS may vary depending on the add-ons involved, reducing unnecessary content can improve the overall user experience.
Troubleshooting Community Folder Issues
When problems occur:
Step 1
Identify the symptom.
Examples:
- Missing scenery.
- Simulator crash.
- Poor performance.
- Visual corruption.
Step 2
Ask yourself:
What changed recently?
- New airport?
- New aircraft?
- Simulator update?
- New utility?
Step 3
Disable recently added content first.
Step 4
Test using your permanent benchmark flight.
Step 5
Re-enable add-ons one at a time until the issue returns.
This systematic approach helps identify the conflicting package quickly.
Best Folder Structure
A professional Community Folder should be:
- Clean.
- Organised.
- Easy to navigate.
- Free of duplicates.
- Free of obsolete content.
- Supported by profiles where possible.
Good organisation reduces maintenance time and makes future optimisation much easier.
Common Mistakes
Installing duplicate airports.
Leaving outdated packages installed.
Keeping hundreds of unused add-ons active.
Mixing unrelated files together.
Deleting add-ons before testing.
Ignoring library updates.
Making multiple changes before troubleshooting.
