I have a .zbd file from my military service with sensitive information on it from 2004.

I have downloaded the ZoomBrowser from Canon, it does not recognize it as a file.

I downloaded the Zebedee Secure Tunnel, but that just creates a tunnel, and is not a file viewer.

I have downloaded a number of free file viewers, but none seem to open this file.

Any assistance you could give is immensely appreciated.

    What does file say? What is the output from strings? What if you just look at it with a text viewer? What size is the file? Apparently it is not anything to do with Canon and I fail to see the reason to install Zebedee...

https://fileinfo.com/extension/zdb says File Type 2 EPSQ Database

with description:

Encrypted file format used by the U.S. military and Department of Defense for Electronic Personal Security Questionnaire (EPSQ) documents; most often used for the Standard Form (SF) 86 Questionnaire, which is used by military personnel, government employees, and government contractors to apply for a Security Clearance.

That seems like what you're looking for.

According to this site and several like it there's a Windows program "DoD EPSQ" that can read this.

According to https://dmna.ny.gov/arng/ocs/epsq_directions.pdf that software can be downloaded from https://sclient.dss.mil/download/w95nt.htm, but that website no longer exists.

Another person had a similar question here: https://www.airwarriors.com/community/threads/looking-for-the-epsq-software.34223/ but not sure if the linked dropbox file is correct (or safe). Good luck.

  • And a silly comment - I would expect any sensitive information to be protected with a password. Do you know it?

  • @tum_ I would guess the "password" is more likely to be authorizing access to the system where the files are stored, not a password for each individual file. (Having worked in an environment with a fairly low level of military security, the first level of "password" is the lock on the office door to get access to a computer that is connected to a secure network...)

  • @alephzero Hmm, reading the question again: "I have a. zbd file" implies the OP already has it in their possession. To be honest, though, I feel a bit uncomfortable even discussing military stuff on a public resource))
