Update File Version

When a user adds a new file to a folder, and there is a file in that folder with the same name, then a new file version is created.

• A new file version uses the same File-Id of the file with the matching name and same Parent-Folder-Id.

• The file upload process is followed and new File Metadata and Data transactions are created.

• However a new UUID is not generated and the same File-Id and associated metadata is used for this new version

• The new File Metadata Transaction points to the new Data transaction.

  • Since the File-Id remains the same, the File Keys for private files can decrypt all versions of that file.

  • For private files, new Cipher-IVs are generated for this new metadata and data transaction

• ArFS clients can now iterate through the state of this file, since it will have multiple versions using the same File-Id.
