How many bytes?

[Captain Utopia]

"Overall view of large file room at FBI headquarters. 1944"





From what I can gather, the large sheets of paper are fingerprints and a small amount of descriptive text for an individual. Compressed, I'm pretty sure the data in that room could fit under one terrabyte. Most of the space in that hall seems to be sacrificed for the ease of filing, rather than storing the data itself.

But any guesses? I arrive at the terrabyte figure by assuming an upper limit of one megabyte to store all information on an individual, and that I expect there may be several hundred thousand individuals listed, but less than one million.
