Thanks @Andr. I have now. Didn’t realize Markdown was an export option. However, the files are named “foo.markdown” rather than “foo.md” so Obsidian doesn’t see any of them. That’s easy enough to fix with a script, but I’m wondering what other fixes will be required.
Before I dive into all that, I wanted to see if there were any resources (e.g., scripts) or tips out there in the community. It looks like there are some former Zim users here so I’m curious how they migrated.
