I'm looking for a personal wiki that has a desktop version.
I've come across recommendations for zim-wiki and tiddlywiki-online, but I'm not sure if these are what I'm looking for.
I have a lot of material either as Word documents, Excel files, PDFs etc. that I'd like to connect via a wiki style software where I can make notes and add/attach links to various files as necessary.
I'd also appreciate if there is one that has a backup feature, or portability between Mac and Windows.
Update: I have tested Onenote for almost a week pretty extensively. While not quite a wiki, it seems to be doing a great job in helping me organize/link documents and take notes. It's a note-taking software more than wiki. I'm not going to uptick an answer since I'd rather more suggestions come through to identify a good wiki-style software that isn't complex as MediaWiki.
