Will updating files be reflected to all nodes copied it?

If I update a single file, will be updated to its latest version on all nodes in the network that previously copied the updated file?

No, if you update the file and add it to IPFS again, it will have different hash. IPFS uses hash as unique identifier of a file.

You can use IPNS system to keep reference to the newest version of given file.
