I'm following up on message below. We are still having difficulty viewing the files on Blu-Ray discs 102, 103, and 104. I'd really appreciate it if you would be able to connect me with whomever prepared those Blu-Ray discs for us, so we can figure out the best way to access them. Thank you very much for your help!

Just looping you in — thinks that these files can't really be opened. Instead, the name of each zip file seems to point to a specific location hit, and what's inside each zip file seems to be the metadata of that hit. Do you happen to know the agent who provided these files? It might be best for us to reach out to them directly to confirm this, and possibly have them compile the data in a spreadsheet (or something like that) instead of thousands of individual zip files. Thanks so much!

These may be some type of system file in a cellular network and not meant to be opened. I'll have to research more.

It looks like the files that should open are .3GPP1IRI files, but I'm not sure how to best view them. suggested Quick Time Plus, and while it did open the file, it showed only a single line of text. I'm not sure if that's the correct application for viewing GPS files such as these. Would you be able to point us to a specific app or converter we should use for this? Thanks so much for your help!
