Could you advise how I could move the app (desktop) and all the data to another harddrive.
I am running out of space.
Install the app on the other hard drive. Back up your records to the new drive. Open Manager on new drive and Add Business. Done.
Make sure you have same or newer app version on new drive.
If you want to move data to another hard-drive (within the same computer), then go to About Manager and click Change button to set select different directory.
