How to open massive database files?

Which programs do you guys use? I've tried a handful and DB Browser seems to be the most compatible. If I try to open something massively, like 100gb+, I get not enough memory error. I have 64gb and it seems like I genuinely need 128gb of ram? Is it possible to open massive files like these without buying 128gb of ram? Any file splitting programs seem to either not work or are paywalled, so I would prefer to stick to just opening the normal file.

Wow, thank you! That program worked wonderfully! It barely uses any memory and no lag when scrolling

You don't need as much RAM as the file is large. A good program should read/process it in chunks or memory map it.
I write a python script with pandas and a reasonable `chunksize`

If you are on linux and want to use say Vim, then try opening Vim in a GPU-accelerated terminal emulator, example: Kitty, Ghostty
