I can't understand you requirement. Normally a opened file ,if deleted , will remain available as long as they not closed.
For example,
open mp3 file and play in music player. After few seconds delete the file from it's original location.
Though file is deleted , since it was opened my music player application , you will continue to hear the song. Once the song is completed and if you play the next song previous file is closed ,hence lost.

Doesn't work like that in Linux. If you tell the computer to delete a file, it's going to delete the file. You'll have to program in your own failsafe if you want it, or copy someone's work.

There are several ways to synchronize a cp, that is followed by an rm

Easiest would be to to it in a script:
cp <FILE> /some/where/ && rm <FILE>

The rm part after && will only be executed, if the cp returned an errorstatus 0.

Or you could use rsync.
It has an option to delete the source file after succesfull sync.

One could also think of lock files or more sophisticated methods.
But actually, I am not 100% sure, what you want to achieve.
