How do I remove the installer files from Mac Air

[pectin232]

I just installed a few applications like iWork, etc. I have backup on external. I see some remainders of files. How do I remove those installer files.

You drag them to the Trash like any other file, or do you mean something else entirely with "remainders of files"?

What installer files are you referring to? Where are they?
