Importing charts
You can import charts by directly copying them from a USB stick, or across a network (e.g. your wireless router network) using the MacOS Finder application.
Astro Gold for Mac OS keeps its chart files in the "Documents/Astro Gold" folder, by default. You can use "Finder" to manually copy/move any external chart file (*.SFcht, *.dat etc) into this folder if you wish. Charts can be imported for example from Solar Fire, Astro Spark or from the Astro Gold iOS file sharing folder in iTunes. You can also import Time Cycles Io software chart files.
Exporting charts
1.You can export whole chart files by using Finder to manually copy the chart files from Astro Gold's chart folder (which by default is "Documents/Astro Gold") to your desired destination folder.
2. In Astro Gold's "Saved Charts" dialog (used when opening or saving charts) you can select individual charts to export, and then create or select the destination chart file into which you wish to export (copy) them. Once the charts are selected you do this by then navigating to any folder of your choice (using the File dropdown 
in the top left of the screen) and accessing (or creating a new) chart file directly in any other folder.
Then click on the Copy button to copy them into the other chart file. For example the other chart file may be one already in your Astro Gold iOS folder. See Copying Charts for full details
3.You can also attach any chart file to an email to send to someone else in the normal manner.
The iCloud Drive is a service for storing files in the cloud, or on the internet in other words. It is a service provided by Apple that you have to sign up for, and when you do you get 5GB of free storage of your computer files on your iOS or MacOS devices (iPhone, iPad, Mac computer etc).
Astro Gold for Mac OS is also able to (optionally) store its charts on the internet in the "iCloud Drive". When you do this all your Apple devices can access the same chart files, which are automatically kept in synch, and remain there even if you delete Astro Gold off your computer or another device.
•You must have iCloud enabled for the device(s) on which you want to use this feature, following each app's prompts to switch to "iCloud Drive". In particular note that you must sign on to the "iCloud Drive" with the identical Apple ID on each device you want to use this feature.
•The first device on which you enable this feature will be the one whose chart files are moved onto iCloud. When you enable this feature on any other devices later on, they will lose access to their own local chart files, and instead link to the chart files moved across to the cloud from the first device that was enabled to store its files on "iCloud Drive".
IMPORTANT: After setting up "iCloud Drive" on the first device, before you enable/activate the "iCloud Drive" on a second or subsequent devices, it is a good idea that you check these subsequent devices for any charts that only exist on these devices.
If you have such charts, and want to keep them, first export those charts to the first device (for example, send them as an attachment to an email), and then open them in Astro Gold on the first device. This will then automatically put those charts on the "iCloud Drive", and so you will not lose them when enabling iCloud on these subsequent devices.
<< To set up iCloud Drive to store your charts on it
The first step is to make sure that you have the "iCloud Drive" turned on:
1.Close Astro Gold
2.Click on the Apple menu icon in the upper left corner of your Mac.
3.Click on System Preferences.
4.Click on iCloud.
5.Tick the box for "iCloud Drive" to enable it.
6.Once you have enabled it, you can check to make sure it shows up under Favorites.
Now you are ready to tell Astro Gold to use the "iCloud Drive":
1.Open Astro Gold (and it should automatically communicate with the "iCloud Drive").
2.Start off by selecting a chart, by opening one in the normal way (see Opening charts).
3.As you do, in the "Saved Charts" dialog click on the File button. In the window that opens, on the left hand pane in the iCloud section you will see your "iCloud Drive".
4.Click on it and in the pane on the right you will see the Astro Gold folder.
5.Click on the Astro Gold folder, and your chart files will be displayed on the pane to the right of that.
6.You can then select a chart file and click on the Open button.
<< How many charts can be stored on the iCloud Drive?
You can store up to 5GB of data for free on your iCloud Drive. This includes all of your files, not just Astro Gold files.
You may need to pay for extra storage. However each Astro Gold chart takes up only about 200 bytes of storage, so even a chart file with 1000 charts would only take about 0.2MB of storage. Hence in practical terms any extra storage space requirement is much more likely to be prompted by your other file types.
General information about the iCloud storage service
Any file you put in the iCloud Drive stays in there until you delete it from the iCloud drive.
Apple has hundreds of computers (called "servers") on the internet, all interconnected, which is what makes up the iCloud storage system, and your files are stored on some of those computers.
Your files are not just stored on one computer though - at any one time there will be several copies of your files stored on different computers. Therefore if one computer goes down for some reason, your files aren't lost because there will be copies of them on at least one other computer.
See above for setting up iCloud on your MacOS computer, or see here for setting it up on other devices: Set up iCloud on your iPhone, iPad, or iPod touch - Apple Support
Once you have done this you will have an "iCloud Drive" folder on your computer or device that you can store files in. This folder and its files will be replicated (mirrored) on any other devices where you have set-up iCloud, and also in your iCloud account on the internet.
To access your iCloud Drive on your computer/device you can just go to it directly the same way you access any of your folders and files on your computer or that device. For example on Mac computers (they have the MacOS operating system) you can use the "Finder" app to find your folders and files, and in Finder you can clearly see your iCloud Drive listed in the left-hand pane. Just double-click on it to open it.
****
To see your iCloud Drive on the internet though, you will need to use a browser (on a Mac computer use the Safari app), and then type in www.icloud.com and press the Enter key. You will then have to log in with your Apple ID, and enter your Apple ID password.
Once you are in there you will see several icons, and one of them says iCloud Drive. Double-click on it to open it, and you will see perhaps several things, but there will be one or more folders called "Astro Gold". If there is only one, double-click on that to see your chart files. If there are more than one Astro Gold folder you may have chart files in more than one.
In any event, if you see your chart files in there, they are safe, no matter what.
