    ​Great to see a good crowd in London on Tuesday.
    One for @Peter Horsboll Moller to follow up please.

    Could you post where we can find your tool for merging thousands of asc files
    (as per the Environment Agency LiDAR data) with MapInfo Pro Advanced.

    Sure, you can find the tool here, @John IeversmbMapInfoRasterTool on Github

    The feature you are mentioning lets you select a folder with sub folders.
    The tool creates a new MRR for all the ASC files in each sub folder​. You should end up with as many MRR as you have sub folder, if they all hold ASC files.
    It will also create TAB files for all the ASC files using the coordinate system that you select. If TAB files already exists, they will get overwritten.

    Don't use it in anger as I haven't tested it with thousands of files :-)
