It was in this folder that I had looked but unfortunately all the folders they contained had been reset.
No, not to my knowledge, it had worked well for several months. However, the time this happened, it followed a sudden shutdown of Windows during a restart (like a crash).
Is it possible that the data could be corrupted if the crash occurs at the exact moment when the old files are deleted and before the new files are created?
I also often had the message "the last modifications may have been lost" when starting the software.
