Intro to IPFS

Retrieving Files



We’re now online, so we can try downloading a file from the network.

[email protected]: ~/ $ ipfs cat /ipfs/QmW2WQi7j6c7UgJTarActp7tDNikE4B2qXtFCfLPdsgaTQ/cat.jpg
cat.jpg
[email protected]: ~/ $ open cat.jpg

Here’s a kitty from the decentralized web!

If everything is working properly, you should now see an image file open with a picture of a cat! This image file is now on your computer, but you didn’t get it over HTTP, and it may have been downloaded from any of hundreds of IPFS nodes around the world.

If you're following along with the web client (at https://try-ipfs.theblockchaininstitute.org/) then you won't be able to use the path shown above. Instead, you'll need the IPFS Address of the file. In this case, we aren't using any encryption, so the address of our cat.jpg will always be the same hash of the file. You can get the file from the IPFS web example by searching for the ID/hash of the file:
