When I think of future civilizations pouring over our archives I imagine they'll have invented new technologies that give them capabilities to discover facts in ways we cant imagine. So long as the bits are still correct I could envision an AI that can basically "crack" the codes and bring about a human readable version. Its sort of like cryptanalysis in that you have a bunch of "cipher" texts (eg, .DOC files) and maybe you even have some known plain texts (.txt files with similar file names) . Yes i realize .txt is ascii and that is a cipher in itself, but I am presuming that a 1-1 keyless mapping will be easy for them to figure out. Encrypted stuff maybe totally unreachable though besides brute force.
