Migrating from MongoDB Atlas to self managed Mongo (EC2) server

There is an abundance of info about migrating TO Atlas but not too much I could find specifically about going the other direction. I am migrating a collection which is 250GB in size. I have tried using mongodump from the remote EC2 server connecting to the Mongo Atlas instance however presumably due to the large collection size this keeps failing. I have also read that mongodump is not great for DBs of this size but I could be wrong. I was able to download a backup .tar.gz file from Atlas and move this to the the remove server. The file contents are below. Is it possible to restore these in to a fresh mongo setup on the EC2, or will these only work for the environment they were taken from? Here are the files available in the backup:
