try this:
[ext[open|file://C:/Data/TiddlyWiki Janna/Documenten/to/wiki/ipad_gebruikershandleiding.pdf]]
* "ext" is for "external link"
* the word "open" appears as the clickable link text
* the remainder (following the "|") is a Windows local path/file reference
* use *forward* slash in all paths, even in Windows.
Also, if the the target .pdf file is in the same folder (or a subfolder) as the TiddlyWiki document, then you can use a *relative* path. Something like this:
[[open|ipad_gebruikershandleiding.pdf]]
or
[[open|some/subfolder/ipad_gebruikershandleiding.pdf]]
enjoy,
