Your assets are bundled into a custom '.pmrk' folder type. This is not to be altered, and is merely a physical copy of your proof which is saved to your local machine. This can be backed up onto physical other devices, or stored elsewhere. The package file can be uploaded which will then be analysed in the browser to run checks against the system and on-chain records to ensure it matches, along with checksum verifications to ensure no files were altered, even accidentally. Small changes are noted to the user, in the event that the user perhaps does this accidentally. PeerMark is STILL able to detect if the contents of the file are accurate to the original, and provides a 'score' on how far from the original file it deviates if altered.
