You can add any type of content to IPFS. In this case we will put some text content into a
.txt file called
mytextfile.txt and put the text
IPFS TEST - VERSION 1 in it.
You can read the file's contents using the cat command:
Save the hash that IPFS returned. This is the content's cryptographic hash. If the file's content changes, the hash will change, but if the file's content remains the same, the hash will always be the same.
Downloading files from IPFS
You can now try to download the file you've just uploaded to IPFS
How IPFS identifies files
IPFS tracks content based on its cryptographic hash. This hash uniquely identifies exactly that content. As long as the content stays the same, the hash stays the same, but if the content changes at all you will get a different hash. If you have two different files that contain identical content, IPFS will track that content with one hash. The filenames are different, but the content is the same, so the hash of the content will be identical.
