1. How can I open .7z files?
    The output files provided by LOBSTER are compressed using the open source tool 7-zip (external link). 7-zip has better compression rates than standard .zip files and thus reduces download times even further. Windows, Linux and even Mac versions are available.

    LOBSTER's output is provided in the CSV (comma-separated values) format. CSV files can be opened by most editors, e.g. Wordpad in Windows or Microsoft Excel, and can easily be read by numerous statistics and econometrics software packages. Please refer to the manual of your favored software for details.
