NTFS, fat32, exfat, could I theoretically create my own filesystem? If so would my computer even be able to work with most files or connect to other devices?

Building a filesystem essentially means linking a directory of filenames to physical blocks and handling CRUD operations. It’s not that hard. The hard part comes when you go beyond the basics to build something efficient with useful features. For example, fast access, journaling and fragmentation are all challenging topics. You can try without messing with the kernel by creating an in-memory filesystem (essentially a block of RAM) and playing with the I/O.
