Torsten Curdt commented on COMPRESS-54: --------------------------------------- I've only gathered libraries for implementing this. For RAR I found sources for o rarlib (GPL) o unrar (sort of free but cpp) For 7zip I found o p7zip (LGPL + restriction, written in C) o j7zip (LGPL) And there are other algorithms (and libraries) to implement as well: ARJ, CAB, ... But I fear some of those implementations need to be hosted somewhere else (due to the licensing). I'd suggest to create a github project for it. > Add 7zip or RAR archive support > ------------------------------- > > Key: COMPRESS-54 > URL: https://issues.apache.org/jira/browse/COMPRESS-54 > Project: Commons Compress > Issue Type: New Feature > Environment: N/A > Reporter: Tim Pinet > Priority: Minor > Original Estimate: 30h > Remaining Estimate: 30h > > Has anyone looked into adding support for 7zip and RAR file types?
