What does Ido do to a file in Emacs?
Think about how often you switch buffers, open files or navigate directories in Emacs. When Ido is enabled it replaces the existing key-, and command bindings with its own, “Ido-powered”, versions. Most ido commands are named “ido-xxxxx”; so find-file becomes ido-find-file, and so on.
How to find a buffer name in Ido mode?
With Ido you’d type a few characters until you find the match, or until you narrow down your list of matches to a manageable subset, and then press RET. Even better, with fuzzy matching you can find things even more efficiently. So the above buffer name could be found by typing “cgf” – c for Customize, g for Group and f for Foobar. Magic.
What does Ido stand for in command line?
When Ido is enabled it replaces the existing key-, and command bindings with its own, “Ido-powered”, versions. Most ido commands are named “ido-xxxxx”; so find-file becomes ido-find-file, and so on.
How does the Ido-powered completion engine work?
The “Ido-powered” completion engine matches anywhere in a name, instead of just the beginning.

What to do with Ido mode in Emacs?
Ido is capable of ignoring (that is, by omission) buffers, directories, files and extensions using regexp. I would recommend using M-x customize-variable RET variable-name-here to customize them unless you are comfortabe editing Emacs lisp directly.
