What is a bootstrap file?

Bootstrap: What to do guide:

- Download and install the Zeitcoin wallet software run it and then close it.
– Download the latest bootstrap file (via website).
– Copy the bootstrap.dat file in the folder \Users\YOUR_WINDOWS_USERNAME\AppData\Roaming\Zeitcoin (for Windows) or in the Zeitcoin data folder for other OSes
– Run the Zeitcoin software to import most of the blockchain locally and then to download only the rest and synchronize the client

This will get you up to speed and running in no time and much faster than running the Zeitcoin client and waiting for it to download and synchronize the complete blockchain from the start to the most recent blocks.
