When in Vim insert mode, is there a way to add filepath autocompletion?

Question

I write a lot of shell scripts and I am constantly having to enter in filepaths. I am wondering if anyone knows of a way to get Vim to autocomplete filepaths while in insert mod

Answer 1

I experienced similar problem. I found solution like:

    sudo apt-get install realpath

And in VIM naviagte to file with in normal mode type:

    :r !realpath /path/to/file

When you are navigating in non-insert mode after !realpatch you are able to use our key button.

VOILA! TAB is working again!
