Large miscellaneous archive of about 1.13 GB whose Russian name translates roughly as assorted useful material for mods, mats and tserver, and other things. The name does not list the contents, so expect a mixed collection of repair or service utilities rather than a single document. Extract it to a separate folder and scan it with antivirus software before running any executable inside. Review the folder structure to find relevant tools, and keep the original archive in case files need to be restored or compared later.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @videocard_notebook_resistance. Enginerys does not host this file.
