I use Tixati 2.58 on Win10(17134)-64bit and I've enabled the option to keep a daily backup of the settings. For some months I didn't run Tixati and when I started it again it began writing many backup files to the HDD until it filled all its free space (I had low free space but it would have been enough if Tixati didn't start writing so many backup files). Perhaps Tixati should recognise that it wasn't started for a long time and that there is no need to keep so many backup copies since one would be sufficient.

Well, there might be two possibilities.
