find / -name unrar
/usr/syno/bin/unrar

they use unrar for rar

sorry I moved recently
just got to get the cable done

now case with Synology is reopen
will let you know if there's any devellopement

I've opened a case case id 620253

I've send a rar file so they could replicate the issues

I'll try to keep you updated

yes that's what I've been using to extract the file then sort them with filebot when I was away from home

maybe the issues is not with Filebot but with Synology 7z I have the same error with multiple/single part rar message when i use /usr/syno/bin/7z t /volume1/Download/Torrent/Auto/somefolder/somefile.rar Error: Can not open file as archive from the web UI I can extract fine. single 7z file is fine ...
