I have multiple svg files in a single folder and only a few of them have thumbnails - all those less than 10MB have thumbnails and all those larger do not. Is there a size limit for generating thumbnails in finder? Is there some way of increasing that limit?
Finder will not generate thumbnails for files larger than 10 MB, unless it's a package with a Quick Look preview pre-generated, such as a large Pages document. It doesn't seem to be possible to increase the limit currently. You can provide feedback to Apple here:
