External clipboard considerations
First of all, avoid the external clipboard! You should use the internal Tree Clipboard, unless you want to copy⁄paste to⁄from another TreePad program.
But if you really must use the external Tree Clipboard, there are certain things you need to be aware of.
(1) Do not copy⁄paste a very large tree to the external tree clipboard, but limit the size of the tree which you copy to a couple of hundred nodes. The reason is that the file format of the external tree clipboard has a maximum recommended size of around 20 Mb (excluding images and icons). Also, a very large tree can take a lot of time copying to harddisk. The internal Tree Clipboard has none of these limitations.
(2) As the TreePad Clipboard is really a special form of ASCII text file and not encrypted binary code, you can read it with a text editor - and so can anyone and anything else including malicious spyware. Once you have made the first copy in TreePad to the external clipboard, the TreePad Clipboard files will be created, and remain in the Windows temp directory.
You can order TreePad to delete the clipboard file on shutdown.
This will move the file to the Windows recycle bin.
You can change TreePad's shutdown behaviour using the options screen, Menu: View⁄Options, category: TreePad⁄Shutdown
At shutdown, TreePad gives you three Clipboard options:
- Automatically clear TreePad clipboard when TP closes
- Ask whether or not to clear TP clipboard when TreePad closes
- Do not clear TP clipboard when TreePad closes
(3) Finally, since the external TreePad clipboard is a file inside the Windows temp directory, do not use the external TreePad clipboard for long-time storage, since it can be overwritten by TreePad, and the entire temp directory can be periodically cleaned up by other programs or by Windows itself.
