Thanks for pointing me there, but I do not think that this is documented sufficiently well here:
It would be in everybody’s interest to improve the UX instead of repeatedly suggesting to clean folders manually, even for testers. Until then, the suggested steps could be easily automated and a tool provided with MSFS. Less support required, yay.
Bonus points if time could be saved by only partially cleaning files: Looking at my MSFS 2024 folder, it’s 625 GB and would probably take half a day to download again (mostly limited by server speed).
Pointing to random pages with specifications is not helpful. It’s like pointing to Asobo’s recommended spec of GPUs with 8 GB VRAM.
