I'm running out of space in wubi. Online wubi help didn't help much since they suggest creating extra virtual disk space(similar to having a diffrent partition i guess) . None of them speak about increasing the size of /root disk space(or root.disk). I store all files in space shared with windows or external disk and use ubuntu only to install and use softwares and browsing. So how do increase the available space for installing more softwares?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
First of all you can clean up something to recover some space, for example with
to remove the packages cache, and you can also remove the browser cache.
Next, if needed, you can move one of your system directories, e.g. /var, to a separate partition, this post can be of help.
As I understand it, wubi installs Ubuntu on a raw disk image. In that case, it should be possible to expand the file. This would expand the "disk", but not partitions, so you need to expand those afterwards, and then expand the relevant filesystems.
I have never actually done this myself, but it should work. But you will have to figure out what file format the .disk-files use. It's most likely RAW images, in which case expansion is a piece of cake. You can find lots of resources about that on the web. Partitioning would be done from within the running Ubuntu, likewise the expansion of the filesystems, which you can do with resize2fs. (You should read its manual by entering man:resize2fs in Firefox, or typing man resize2fs in your terminal.
It isn't complicated.
