There are a couple of ways to to this, the best method is to:
More detailed information about upgrading Plant Base can be found here.
You can simply copy the database files from one machine to another, replacing the database on the target system.
But if the destination machine also has custom information that you wish to keep, for example Plant Lists, then use the Import function instead:
Simple - though we love taking plant photographs, there are severe time and opportunity limits. Most of the pictures in Plant Base are own own, plus some from kind contributors. We always respect copyright rules and avoid using any of uncertain origin. More are being added continuously, but you can also include your own from photos you have taken or the many other sources that allow personal use - see How to add pictures.
While Plant Base in not running, use Windows Explorer to to move or copy one or more of the database files to another location - a different folder or disk. When you start up Plant Base, it may complain that it cannot open a file. Type, or select the new file path with the open dialog and click the Continue button. If the original files are still in place, open the Change/re-open dialog from the "File" menu. Check the correct files are open in the Help | About display.
Yes, as of March 2014 there is a native Mac OSX edition of the program. At this time it's still regarded as a Beta release but is perfectly OK to use. It will run on OSX 10.6 or later. At some time in the future we also plan to write a native Linux edition. The database file are always the same and can be copied between systems of different types.
Use the PlantSelector screen to set Plant type = tree. Run the search and in the results windows, double-click on any interesting name. The PlantMaster screen will now show a "Selected" toggle button and when you scroll the records only trees will be shown.
It is also possible to create your own custom database copy, with only the plant records that you are interested in - see How to create a custom content database
That may be correct. Plant pictures are each shown in a separate window and usually remain open until you wish to close them. So pictures for several different plant varieties can be on screen at one time. Useful if you want to compare them. To close all the pictures quickly, use the Window menu item "Close All Pictures". However you can also close picture windows automatically when you move to a new plant. This is controlled by a program configuration option. Open the config screen, click the pictures tab and check or uncheck the box.
Not directly, but Yes! Individual plant data sheets, Plant Lists or pictures can be printed directly, put printed output is otherwise quite limited. However, there is a function to create a disc file in simple HTML format. This output file may be further modified using another application, such as word processing, to make a customised printable report.
