It'd be more accurate if the horcrux files were embedded into other files that had to be deleted using an arcane command from the horcrux program to resurrect the original file...while the original file remains in a half existing unreadable state until resurrected.

ETA: For even more accuracy, increase the 'readability' of the file(for text only I guess) with each horcrux deleted. Allow them to be added one by one so the original file slowly 'increases it's power'.
