This guide is not acurate anymore. In my pc store version the folder C:\Users\Username\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages does not exist anymore.
Anyone has a good guide how move pagage to another folder when going to beta?
If you want to point MSFS2024 to the new location, instead of copying your backup back to the original location, you can set the new folder in the “Marketplace”-> “My Library”-> Settings-wheel:
This folder should then contain what is in your packages folder.
Maybe also backup the ROLLINGCACHE.CCC, as that’s where MSFS2024 actually stores it’s streamed data. You can point MSFS2024 to a different folder for that as well in the settings menu where you can set the size of it.
