the default backup folder is within the techmanager program folder named 'backup'.

there are 3 'part' folders inside, one for each partition.

if you accept the default path the program finds them automatically, alternatively you can set your own path to save and load.

a backup of a couple of hundred midi files of 3 or 4 MB takes half an hour or so. a backup of my main partitions takes all night for each of them so just leave it alone until it tells you it is finished.
