If you right click a file in Nautilus and select Compress, then you get a dialog where you can choose a compression format and a filename. If you click on Advanced, then there are settings to split and compress the file, but it's deactivated/insensitive. How come and how do I activate those features?

Edit: In an answer below, it has been suggested that it has something to do with rar. But I have that installed, and I don't get the options to split.

Where is 'compress' did they remove that feature? – user56413 Apr 24 '12 at 15:09
No. Right above Properties. – Jo-Erlend Schinstad Apr 25 '12 at 7:48

Only some archiving tools support splitting. One of them is RAR -- package rar (but it's shareware and you need to buy it after 40 days -- Shareware in Ubuntu repositories? (RAR)) and another is for example 7zip -- package p7zip-full. You need to install one of them (I suggest 7zip because it's completely free).

You can also create a sigle archive and then split it into parts using split command (or HJSplit for GUI).

when I installed p7zip, then I could split the file if I choose 7z. If I install p7zip-full, then I can also password protect it. So, in that regard, my question is sort of solved. But I still can't select rar. – Jo-Erlend Schinstad Aug 19 '11 at 7:43
And do you have package rar installed? Packages unrar and unrar-free are only for RAR decompress support. – Vojtech Trefny Aug 19 '11 at 8:43

To activate the split option, select .rar from the file extension drop-down box.

I can't select rar, even though I have unrar installed. – Jo-Erlend Schinstad Jul 27 '11 at 18:17
@Jo-ErlendSchinstad you must install rar first: apt-get install rar. Hope this late comment can help others. – Fernando Kosh Aug 1 '14 at 3:33

Try replacing rar by unrar-free or the other wise around.

This can be done by simply

sudo apt-get install unrar-free

This doesn't let you create rar files...only extract them. – Cerin Aug 1 '14 at 19:53

Using p7zip-full, as Vojtech Trefny suggested, works, but didn't enable me to choose rar as compression method. Neither did unrar. However, installing the package "rar" does present that option, and if you open Advanced, all options are sensitive.
