I use pycharm for this and in general it does a great job. At work we’ve got some massive repos and it’ll handle it fine.

The “find” tab shows where it’ll make changes and you can click “don’t change anything in this directory”

If you’re willing to deal with managing it, 125gb on s3 seems to cost about $3 per month.

I watched a YouTube video where a dev was optimizing unity code to match the size of data that is sent to the cpu using structs just like this.
