To backup your Custom Datasets from a previous installation, you have to first
go to your local-datasets folder (Default path: C:\local-datasets),
double click on the custom folder, and copy all the contents to another
temporary location (like your Desktop for example). If your custom folder is empty,
this means you don’t have any custom datasets and you can disregard this section.
Default location for the custom folder.
After the installation of the new version of SOSx, you can copy the backed up
contents to the new local-datasets/custom folder in the location where you chose
to install SOSx.
(Default Path: C:\Program Files\NOAA Science On a Sphere\SOS Explorer Desktop\local-datasets\custom)
