Re: Unity system wide search
If you in a folder/nautilus/ or what the file mangare are called. Choose in the top menue Go--> 'Computer' search I think all your attached harddisk get searched. Or if you choose 'file system' in the dropp-down alternatives under local. There you also may choose to just seach one hdd, I think.
I'm also new to Unity
Ubuntu 14.04LTS 64bit, 14.04 Lubuntu 32-bit on eeePCs and OSX on a G4 800MHz iMac (iLamp). I think I have an W7 on one of my Virtualbox machine under 14.04LTS?
