I’m on Mint. I have two partitions, one at 100GB I set up for the main OS installation, and another 1.9TB installation I use for storage. But the first partition is getting some storage issues, which comes partly from Timeshift (which I already redirected) and partially from Steam, specifically Proton. I want to redirect Steam onto the larger partition, but the space Steam takes up in this way is taken up by several smaller files and folders that add up to a lot, so I feel unsure about how to change things properly.
And a follow-up question, is it safe for me to expand that smaller drive with Gparted or something, or would that put the data on it at risk? Since it’s the OS partition, that’s important data.
If all of the proton stuff lives underneath a common parent directory, you could copy that directory to your larger drive, and then bind mount the new location (bind mounting effectively mounts a directory underneath another directory)
