Archivo uses it without modification to the licensed components. The corresponding source is available from the upstream 7-Zip project, and the LGPL permits you to obtain that source and relink or replace the component.

RAR archive extraction uses the UnRAR utility (via node-unrar-js). Under its license, the UnRAR source may be used to handle RAR archives but may not be used to develop a RAR-compatible archiver. Archivo uses UnRAR solely to read and extract existing RAR archives.
