Read the following context and choose the best option to answer the question.
Context: So on my initial syncs , none of my unusual file types transferred ; plus I had to hand - edit out m4v and mp4 to keep my video collection from slowing down the works . Once edited , there was no " revert to standard " button option , so it 's a good thing I wrote down the names of the file types that I 'd taken out . The program is just marginally stable rather than fully stable .
Question: What may happen after i finish editing ?
Options: 
A. I lose my file copies .
B. I make sure that i have file copies .
C. I decide to convert back to the old files .
D. None of the above choices .
