"Unlike a Bates stamp, a hash mark cannot be added to a native file directly because this would change the file and create an entirely new hash mark. However, you can modify the original name of the file to include the hash mark abbreviation because only the contents of a file are hashed, not the file name. Thus the original name of the computer file could be followed with the hash mark abbreviation; ""Bill47.doc"" would become ""Bill47#A5D.7C1.doc."""
