A similar situation in my project. My platform was on a long mission. During it, the battery was discharged to 0. When I found it, I opened the SD card from the autopilot. Unfortunately, the logs are illegible. There is a folder on micro SD with files called STRG25.bak and many simillar, each of 16KB. How do I make a normal .bin or .log file out of it?
