You're correct. Open as Untitled, Edit, Save As .indt
If you're overly concerned, rename the first as file.indt.bak
You would still be able to drag it into ID in the future.
Thanks for the answer. As I'm always trying to learn more about InDesign... out of curiosity, what does the .bak suffix mean?
Thanks for the screen capture. I've probably looked at that feature a thousand times, and have completely disregarded it's existence.
Most helpful and appreciated.
It is the common extesion used when a system or user overwrites a file, denoting backup. Redundant backups use bac. It's just my convienient way to keep a backup, the OS will no longer show the InDesign icon.
Bob has a good reply above
(1) You can always open a regular document as an untitled copy -- use the bottom radiobutton for that.
(2) Legacy documents -- older than the version of InDesign you are using -- will show "[Converted]" in its title bar and will attempt to "save as", and -- quite annoying -- in the last folder you visited, rather than the folder you opened it from.
