Ext2ifs is a tool that lets your computer talk to a special type of storage device called an ext2 file system. Think of it like speaking a different language – your computer normally speaks one language, but ext2 file systems use a different language to store and organize files. Ext2ifs lets your computer learn that new language so it can access and work with the files on ext2 file systems.
Imagine you have two toy boxes with different designs: one has drawers and the other has bins. If you learned how to navigate the drawers in one toy box, but then needed to access toys in the other toy box's bins, you'd need to learn how to open and use the bins too. Ext2ifs is like a toy box translation guide that helps you learn how to use the bins in the ext2 file system toy box.
