I understand what you’re saying. What I’m telling you is, while this check could be done to verify files for Windows Resizable images, all the others are copied in a format of d{disknum}p{partitionnumber}.img
I can add a check for the sys.img.000 file, but there’s no common standard that states every disk is always going to be d1p1,d1p2.
Also, how far do we take this? We’re not storing the file names anywhere right now. So if somebody comes in after we’ve created the image and deletes, randomly, some files from the directory, you would be in exactly the same state.
