Why did OneDrive suddenly scramble my files?

I manage a lot of systems and we usually have OneDrive backup turned on by default. It’s really helpful for saving user documents and even allows for restoring files from years ago! I've had my fair share of syncing issues, but nothing as drastic as what you're describing. Maybe check if there’s a setting that was enabled by mistake?

Whether by accident or not, these unexpected syncs can really mess things up! You might want to look into system restore points too; they can sometimes help recover lost files if OneDrive's backups are not working as intended. Just make sure you have your important files backed up in multiple places moving forward!

It sounds frustrating! While OneDrive can be handy for backups, it can sometimes misbehave if settings get inadvertently changed. I’ve always found it works better when configured correctly, especially if you're using any scripts or unusual setups. Could it be there was an update that reset your preferences? Sometimes a clean reinstall of OneDrive helps fix odd glitches too.
