Whilst we don't have any set limits on importing in Dash, sometimes a web browser won't be best to support uploading a large amount of content into Dash at once. By this, we mean:
A large quantity of multiple assets
A smaller quantity of actual assets, but each asset has a large file size
In both cases, this can result in an overall large amount of data to be uploaded into Dash. Therefore, as a general rule of thumb, we recommend anything that equates to over 5GB in one upload to be uploaded via Google Drive, Dropbox, or other cloud storage solutions, all of which are outlined in this article.
