What I would also consider doing is enabling the Windows 10 backup feature, so you can make use of the “Previous versions” tab when inspecting a file/folder.
The “SimObjects” folder itself is tiny, so would cost you next to no disk space.
Go into “Backup settings”, then click “More options”. If you don’t have it enabled, IIRC it will ask you for a location to store the backups, for me this is a second disk. A folder will be created called “FileHistory”.
You can now add a folder to the list.
I use it to back up important parts of my user profile. Once enabled you will see this will populate the “Previous Versions” tab. You can see below I have a folder called “TV”, which has multiple versions. For each I can take a look as it was on that day by clicking Open, or Restore the current version to as it was on that date.
You can also open these backups in File History, which is in essence an Explorer for your backups.
This would make it very easy to restore old copies of your aircraft state files.
You can also find it via the Control Panel:
“Control Panel\System and Security\File History”
But you cannot add individual folders here, only choose a drive, and exclude folders from the backup.
