Hey guys i downloaded a blockchain from the internet which seems pretty trusted but i cant get to import it. This is what i did and what i got as a result:

Seems self explanatory. It does not find the file. That doesn't seem to be a bug, unless you can confirm the file is really there and readable.
I can confirm that the file is there and i downloaded it twice because i thought that the file is maybe corrupt but it seems to be alright so i dont know what i do wrong but im a newbie to the moneri gui wallet
Since this is Windows, try just blockchain.raw without the ./ as maybe this confuses it.
Ok i will try it. Thank you very much for trying to help me :)
Ok i tried to do it without the point but i still get the same error message
Try sha256sum blockchain.raw
If you don't have the sha256sum tool, then anything that reads the file (to check there's no permission issue, etc).
i dont really get how it works to use the sha256sum tool.
Just "sha256sum blockchain.raw", without the quotes.
Do they have to be in the same folder or something? My cmd just says that it is written false
i downloaded winmd5checksum and this brought me some numbers. but i dont know what they mean

You told monero-blockchain-import the file is in the same folder, so it is, right ?

i think so yes
It should be called "blockchain.raw". It's called blockchain here, and Windows thinks it's a zip file. Unzip it, and make sure the uncompressed file is called blockchain.raw.
Also, there's no way it's only 110 MB. It'd be simpler to just run monerod and let it sync normally.


i think i downloaded the wrong file.. It doesn look like this is right.
The File was 34,5 Gb when i downloaded it..
34.5 GB sounds plausible.
Oh FCK me i was totaly blind, there where 2 files in my download directory one was the zip file but the correct download was still there.

I think it kind of worked:

The problem is that my monero wallet still want to synchronize and download all the blocks..

Did you wait till the import finished ? It will take a while.
i think i did yes. but maybe i didnt. when i try to do it again it says permission not granted
And i get a message from win 10 which tells me it cant run this on my pc.
Permission not granted is a windows/filesystem thing, not a monero thing. Make sure you're using the right binaries for your platform too. After you imported a blockchain, the node will still connect to sync the latest blocks, and keep up to date as the blockchain grows. After that, the wallet will scan the local blockchain. This is fine.
Is this all working now ? There appeared to be no bug, just computer issues AFAICT.
