what program command saves a copy of a file under a different name?

The program command that saves a copy of a file under a different name is “Save As” in most software applications.

Quick Scoop

• In common apps (Word, Excel, Google Docs, many editors), choosing File → Save As lets you:
  • Type a new file name.
  • Pick a different folder or sometimes a different file format.

• This keeps the original file unchanged while creating a separate copy with the new name.

Why not “Save”, “Copy”, or “Duplicate”?

• Save : Updates the current file in place; it usually does not change the name.

• Copy : Usually means copying text or objects to the clipboard, not saving a new file with a new name.

• Duplicate : Exists in some apps, but it typically just makes a same-name copy in the same folder (like “Copy of …”) and is not as universal as Save As.

So if a multiple‑choice question asks:
“What program command saves a copy of a file under a different name?”
The correct single answer is: Save As.

TL;DR: Use Save As whenever you want a separate copy of your file with a different name or location.
