Two items are noteworthy.
One is that we moved a few key systems from older 32-bit machines running older versions of RHEL to new 64-bit machines running RHEL 6. As it turns out the magic database that file uses on RHEL 6 is in a new format, and did not work well with our local additions (aka localmagic and localmagic.mime for Linux folks). So my belief is that our file-based format detector threw up its hands more often than usual, and this accounts for the over 1700 unknown (application/octet-stream) format types last month. I think these are good candidates for a follow-up scan to correct the results.
Two, lots of images. I know that we are getting a lot of video and images as part of our Bill and Melinda Gates Foundation MET and MET Extension projects, but I also know that none of the files above is from that project. So where is all of this coming from? One big deposit....
