Hi, I've downloaded a number of RAR files and joined them with terminal to create a .dmg file. However, when I try open the .dmg file it tells me the file is 'not recognized'. Is there any program that can tell me which of the 18 RAR files is causing the problem? I've also tried using Split & Concat to join the files to make the .dmg and that doesn't work either. Any help much appreciated. Thanks.
