Because of Microsoft's poor streaming file mechanism, your default game data is downloaded to the C drive.
Windows users are recommended to use mklink to move your game directory to another drive to free up C drive space.
Here are the steps:

1. Open the game save directory: C:\Users\***\AppData\Roaming\Microsoft Flight Simulator 2024, and move the Microsoft Flight Simulator 2024 folder to your desired location. I moved it directly to D:\Microsoft Flight Simulator 2024.

2. Make sure the file copying is complete and delete the original Microsoft Flight Simulator 2024 folder.

3. Run cmd as administrator and run the following code:
mklink /j "-original address" "-new address"
Here is my example: "***" needs to be replaced with the specific name according to the actual username.
mklink /j "C:\Users\***\AppData\Roaming\Microsoft Flight Simulator 2024" "D:\Microsoft Flight Simulator 2024"

由于微软垃圾的串流文件机制，你默认的游戏数据被下载到了C盘。
Windows用户推荐使用mklink将你的游戏目录移动到别的盘符来释放C盘空间。
操作步骤如下：
1. 打开游戏保存目录：C:\Users\***\AppData\Roaming\Microsoft Flight Simulator 2024，将Microsoft Flight Simulator 2024文件夹移动到你想要的地址，我直接移动到了D:\Microsoft Flight Simulator 2024。
2. 确定文件复制完成，删除原目录下的Microsoft Flight Simulator 2024文件夹
3. 管理员身份运行cmd，运行以下的代码：
mklink /j "-original address" "-new address"
这是我的示例："***"需要根据实际用户名被替换成具体的名称
mklink /j "C:\Users\***\AppData\Roaming\Microsoft Flight Simulator 2024" "D:\Microsoft Flight Simulator 2024"

For people still wondering what the difference between the 2024 and 2020 version of MSFS would be, so far my experience with MSFS2024 has been exactly the same as with MSFS2020 on launch day :

- No pre-loading of game files before launch
- No actual pre-order benefits
- Files downloaded through in-game interface
- This time around in-game install interface does not support mouse control, presumably because it was designed to be 'cross-platform'...
- Saturated servers cause endless download times for a miserable 50GB
- Downloading time counting as 'game time' prevents customers from requesting refunds.

Same issues were present 4 yrs ago, they simply did not learn.

EDIT : I am now 'in a queue' for logging in, due to 'too many people trying to log in at once'. That is very reassuring for a web-based application that promises to stream the majority of it high definition content...

I can only marvel at the depth of the simulation, as it now feels like Boeing was actually involved in building the servers, and someone from Embraer was put in charge of planning the launch.

0/10 launch, I hope the actual product makes up for it when I try again tomorrow.

I enjoyed the short movie about a man an a plane. However, it seemed quite expensive for its length - around one minute. I would wait until the loading screen is on sale before purchase because it does get quite samey after the 70th loop.

Update: They have improved the initial movie with a power point presentation consisting of two slides. One is about a lot of people trying to see the movie and the other one is about not be allowed to watch the movie.
