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 mode, just like when you are in your favorite shell you tab to complete the path of the directory or file.

Extra credit if you can get CTRLD functionality of the shell into Vim insert mode (i.e. to see what files/directories are in the current path).

For file name omni completion, you can use:

Ctrl-XCtrl-F
