I have installed ubuntu in dual boot with windows7, windows 7 (C drive) disk size is 420GB, Linux drive size is 50GB. Now I'm facing space problem on ubuntu. I cannot reinstall any on them and also cannot resize (shrink) the window partition.
I am thinking to move some big folders like /opt, /bin, /sbin, /etc, /usr, /lib /tmp, /home/user/Desktop to some other folder of the Windows drive and create a link for the same in / . Will this effect the linux system in any way like booting, executing commands, starting terminal, running installed apps like java, ruby etc? If yes, then what are the other solutions for the same?
