To speed up the synchronization of a new wallet, you can use the synchronized blockchain files. To do this, you need to run the downloaded wallet and stop it. Then replace the blockchain files (blocks and chainstate directories) in the wallet directory (default for Windows %AppData%\Roaming\btca\; for Linux $%HOME/.btca/*; for Mac $HOME/Library/Application Support/Examplecoin/) with the files from the archive. Run the wallet file again. Synchronization will complete much faster.
