Working on resolving an issue for a client. They had a theft that was caught on their DVR system. Without asking me first, they exported the data to a flash drive and delivered it to police. The problem we now have is that the files exported are not anything law enforcement can open, and the original data from the DVR has been overwritten. The data exported to .TFS files, which appear by structure to be a database file of some kind. I need to find a way to retrieve this data for them.
About the best I have found so far is that I cannot restore the data to the system. That would be too easy, right?
I also found that the system can export to AVI (as I suspected), and have demonstrated how to do this in the future.
If you open the files in a text editor (Notepad++), the header indicates that the format is TFS4.
None of the files are larger that 128MB and they are sequential. Since the files are large, I can arrange for retrieval of a sample from and FTP site if you ask.
So, I ask the Experts, how and to what DB engine do I mount this data base? How do I export after that? I currently do not have the data that was given to law enforcement, but I have a set of data that was exported in the same fashion today.
