URGENT Multi-Segmented file

[yonman]

We have a Multi-Segmented File (v11.65) and the main file has been moved to a backup folder but the segments were not.  The main file is currently open and active by users, as they've not logged off and the file is currently in-use.  Our question is, when the main file has reached it's capacity and when new segments are to be automatically created, will this actually take place?   Will the original segments be preserved in some manner or will they be replaced with a link to the new main file?
