[1.1.94] Blueprint error

[uniqque]

It all started with the reinstallation of windows 11.
Factorio was not on the system disk and I did not touch it during the reinstallation.
When I logged into the game I lost all my blueprints in the blueprints menu.

I downloaded the file "blueprint-storage.dat.zstd" from steam cloud (https://store.steampowered.com/account/ ... pid=427520).
I renamed it "blueprint-storage.dat" and put in "C:\Users\User\AppData\Roaming\Factorio"
An error appears when starting the world:

So I have a file with my blueprints, but factorio can't open it.
I didn't change anything in the "blueprint-storage.dat" file.
What should I do? I hope there are solutions to this problem.
Thanks a lot.

Did you save your user directory before deleting the os partition?

Did you unpack the .zstd file or actually just rename it?

unfortunately, no

I understand this file had to be unzipped?

I would think so, there is at least a compression algorithm named zstd, never heard of the file extension though. Just try if 7zip can open it.

I unzipped it with "Zstandard" cmd app. Now everything works fine!
