The process begin in FileManager::FileManager().

  1. Load the cache (proto buff) -> c.
  2. Give c to the cache.
  3. The cache create shared directories (SharedDirectory) -> S, sub directories (Directory) and files (File) according c.
  4. For each s in S :
    • fileUpdater->addRoot(s) (via signals).
  5. fileUpdater->start() // Start the file updater daemon (thread).
    • For each s in S :
      • scan(s) // Read all directories and files from the file system.
      • restoreFromFile(s) // Give the known hashes from c to the corresponding files.
