Almost a year since last adding something. Clear I got some priorities wrong.
Herewith a simple C++ Cmdline routine called DataTrimmer one can use to trim large and super-large datasets with. Written it specifically with C++ to not have dependencies when running. You should be able to copy the EXE file to any windows machine(client or server) and run it.
Many times IT will extract data in the many millions of rows and normal utilities will not be able to deal with it due to its size.
You simply tell the utility how many rows to include and it will trim the data accordingly.
