It depends a little on how you want to do it.

If you have specific extensions to ‘ignore’ you can just make something like;


And that’ll be it. Only files ending in ‘.crdownload’ will be ignored, anything else are synced as usual. To add more extensions to ignore, add each on a new line in the same style.

If you want to reverse it, and only ‘include’ certain extensions, then you need to do some tricks to make this work:


Where you first define that you want to “not ignore” jpg and png, followed by “ignore the rest”.

The docs also contain some specific examples and explanations as to how it all works. See: Ignoring Files — Syncthing documentation
