Archived thread 2065402 from Ubuntu Development Version. Markdown source: Ubuntu_Development_Version/thread_2065402_File-roller_No_compression_below_10.2_kB.md
i compressed a folder on my 12.10 xubuntu install and it went from 12kb to 10kb i compressed the same folder on my 10.04 ubuntu install and it went from 12kb to 2.6kb i was using .tar.bz2 on my 10.04 install i have file rollers compresion level at maimum
how can i get my 12.10 install to do this?
i made a bug report after the compression level was -66% https://bugs.launchpad.net/ubuntu/+source/file-roller/+bug/1064117
Nice find. 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

here file-roller is 'compressing' but will never go below 10.2kB So - a folder with a number of small files 43.6kB goes to 10.6kB 34kB goes to 10.2kB 15kB goes to 10.2kB 1.5kB goes [COLOR="Blue"]UP[/COLOR] to 10.2kB
The last file-roller in 12.10 to go below 10.2kB was 3.5.3-0ubuntu1 so this changed with the new 3.5.4 release
If this were to be filed upstream it's likely a response one way or the other would gotten quickly (the file-roller maintainer/dev is usually quite prompt on bug reports
3.5.3 you say well i have 3.6 on my 12.10 install
