LEGO MINDSTORMS NXT is programming software for the NXT intelligent microcomputer brick, with a drag-and-drop programming interface.
The .blockplt file stores palette settings for programmable blocks. It supports the way blocks are arranged or presented in the NXT programming environment rather than containing an NXT program itself.
This is a software settings file for the Windows version of LEGO MINDSTORMS NXT. The format is associated with this legacy NXT software and is not intended as a general-purpose exchange format.
Open the .blockplt file with the LEGO MINDSTORMS NXT software on Microsoft Windows. The software normally reads palette files as part of its own configuration, so opening the file directly may not display useful content.
A .blockplt file is a settings file, not a document or program intended for conversion. There is no usual reason to convert it to another format.
