Hmm, you could end up with a fragmented MFT. I think the following three step process would be easy to implement on the premesis that the *.flm file get written completely every turn.
1st.: rename extension *.bak, if there, to *.tmp.
2nd.: rename current existing *.flm to *.bak.
3rd.: rename *.tmp to *.flm
Then continue the action of writing a new *.flm image file...
No copying or moving at all, only two files that flip identity.
Just my two cents...
