Finally ready to switch my final windows device over to linux, but I'm running into a problem. NTFS drives aren't a good idea under Linux, but my 4 NTFS drives are this full. I own zero extra hard drives, and do not want to spend $300 on another one. 
How can I bring these files into Bazzite WITHOUT just wiping everything and re-downloading 10+ terabytes of movies, shows, music, games, and other data I refuse to delete?
They are describing a scenario where enough of the data is steam games that deleting them would create the swap space needed to get started shuffling stuff around in which case it wouldn't necessarily be that wild... you would be avoiding a lot of the headaches that redownloading other stuff would have; high reliability of the files - nothing would be lost, fast downloads, wouldn't be much labor to que them up, you probably won't need all your games right away... your mileage will vary but it's not the worst suggestion for some people who might be reading the thread in a similar situation.
