Not the poster, but I wrote a Tiddlywiki plugin that uses these APIs (https://slaymaker1907.github.io/tiddlywiki/plugin-library.ht...) and I detect multiple write scenarios by keeping track of the file hash (this obviously only works for files which can be read into memory). Assuming you have a folder and not just a single file handle, you could scan the folder periodically and compare the known hashes to the ones on disk to handle moving files. Things would get much more complicated if you want to support both moving and modifying files and you'd need a system like Git for detecting renames.

That's still a shortcoming in the current setup. The API does not yet allow us to "track" a file as it is moved around on disk. So the best thing we can do is upload it from its new destination, keeping the original version where it is (we want to avoid guesswork and ensure no data is ever lost). We can likely optimize this. Would love to see the API evolve so that we can keep persistent file handles even after moving and renaming (including parent folders).

+1 this looks so cool
