Hi Alessio, today I've checked once more the back-up folder of Xmm and it was over 2.5 GByte big! 27 copies of the database with the smallest 98 MB and the biggest 128MB Would it be possible to have the programm keep only the last X (user choice) backups, maybe in a compressed format done with one of these free compression tools dlls? Have a nice day, Marcel.
