When Windows users suddenly discover that their files have vanished from their desktops after interacting with OneDrive, the issue often stems from how Microsoft’s cloud service integrates with the operating system. The automatic, near-invisible shift to cloud-based storage has triggered strong reactions from users who find the feature unintuitive and, in some cases, destructive to their local files.
+1 for Obsidian. Copy-paste to other pc = immediate access without setup. Plug & play. Also free.
If you self host, go Joplin. I was unimpressed with obsidian’s ability to use the same notebook in multiple systems easily, and Joplin lets me easily sync my notebook between systems using a docker container I host as the sync server.
Obsidian isn’t open source, if OP or anyone else is concerned about that.
I use git to sync my md notes instead of obsidians paid sync service also. I’ll never go back to proprietary non-text based notes files.
