I did a couple of quick tests and it looks as though file roller is not actually compressing the tar file, and it doesn't matter which compression method is chosen. Not sure why it has this effect on your files as the command works as expected for other files.
Steps to reproduce: 1) In Nautilus, right click on "backlightx" directory, Compress... 2) Select .tar.bz2 3) Resulting file size is 10.2KB 4) Right click on directory, Compress... 5) Select .tar 6) Resulting file size is 10.2KB 7) Right-click on .tar, Compress... 8) Select .bz2 9) Resulting file is 870KB ** Changed in: file-roller (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to file-roller in Ubuntu. https://bugs.launchpad.net/bugs/1064117 Title: Extremly poor compression for .tar.bz2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/file-roller/+bug/1064117/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
