When you go to the Tree Download page you will find that you have a choice of three types of file:
- Portable Document Format or PDF files (.pdf), or
- Microsoft Enhanced Metafiles (.emf), or
- TreeDraw files (.tdr)
PDF files are the first choice for most people. If your browser does not display the file well simply save it as a pdf file and the use Acrobat viewer in the usual way. PDF format treesare fully searchable.
The emf file type is a Microsoft-only file type. It works well with all recent versions of Explorer but not with Edge. It will not work with Chrome or any other browser. With older versions of Explorer some people experience problems. Sometimes there is a delay of 20 to 30 seconds before a tree is displayed. It may look as though the file is slow to download, but this is not the case because I used to experience the same problem even when the file was stored on my own hard disc.
Any links to trees on this site, other than through the main download pages, are to .emf files, so they should be accessible whether you use TreeDraw Viewer, or not.
SpanSoft's TreeDraw is the program that I use to produce my trees. A free Viewer is available for download from SpanSoft's website at www.spansoft.org - (click on the 'Downloads' link when you get there).
If you save your downloaded tree files in a suitable folder TreeDraw Viewer 'learns' where they are and clicking on the folder icon in Viewer provides you with a list of the available files. You can navigate around the tree with the aid of the 'chart view control' but it is just as easy to click and hold down the right mouse button and then drag the tree in whichever direction you wish. You can search the tree for a particular person (something you can't do with an emf file) and you can also print trees using the TreeDraw Viewer.
If you have the Viewer running while browsing then you have the option to select 'open' in the download window and you should then see an immediate display of the tree. Otherwise save to file and you will then have the option of looking at the tree offline as often as you like.
